Black powder - see blackpowder2.html 

Be sure to read about charcoal as a variable - it is a short read but pretty important. Your choice of charcoal will affect the outcome of most of the formulas below. Use Skylighter Airfloat Charcoal and a rock tumbler for milling if you want to duplicate my results. If you use a heavier duty pyro mill, your BP will be hotter by far and will probably require taming down quite a bit.

BenzoLift

BenzoLift is essentially whistle mix that is diluted with black powder. If made correctly, Benzolift can be very powerful. Be careful - it can be two or more times as powerful as commercial BP and seems to be the answer to the weaknesses of homemade BP - that is, the stuff is powerful enough that you don't have to make charcoal from hard-to-get woods to make a good lift powder. Normal BP made from Skylighter airfloat charcoal makes great Benzolift (about twice as strong as Elephant brand 2fg). In addition, it doesn't take too long to make and it is cheaper than commercial BP. It might be a bit more expensive than homemade BP although that might not be true when you factor in the efficiencies of using it.

Here is a link to how to make simple Benzolift safely: benzolift.html. If you decide to make it, then stay consistent on your process from batch to batch - minor changes in process can affect the power of Benzolift quite a lot.

There is probably no reason to use Benzolift for lifting large shells - Benzolift is in the 3" and less territory! One thing I have noticed - it 'slams' the shell harder than BP does. Specifically, a 3 gram charge of Benzolift in a Double-Voice Cracker will destroy the cracker on the ground - 3 grams of very hot BP will lift it into the air the way it is supposed to. Both these charges, when used in a mortar, lift the shell about the same height.

Since it is much easier to make Benzolift than hot BP (especially if one can't get/make the correct charcoals), here are some small diameter rules of thumb for lift quantities that I go by (your mileage and cardboard shrapnel may vary):

1.5 to 1.75" - 2 grams of Benzolift
2" - 2.5 grams to 3 grams
3" - 5 grams

Over 3" - don't use Benzolift - use BP. Even poor lift powder can often be used for larger mortars.

Rocket Fuels

RP (BP) is 'Rocket Propellant' which is a 18 Potassium Nitrate, 6 Skylighter airfloat charcoal, 3 Sulphur, 2 Aluminum dust (atomized or use titanium flake - very sparky!) mix. That makes it about 62% oxidizer. It was described by Alan Yates.  Ball mill all except aluminum for 24 hours if using a rock tumbler - 3 hrs if using a hobby pyro mill.. Mix in aluminum. Moisten. Press through a coarse screen. Dry. This mixture seems a bit tame but it is safe to use on almost anything. Start with it and work your way hotter. 

RPH (BP) is 'Rocket Propellant Hotter' which is 68 Potassium Nitrate, 17 Skylighter airfloat charcoal, 10 Sulphur, 5 Aluminum dust (atomized) and riced using the same method as RP (see RP above). Used for rockets up to 1/2". 1/2" rockets must have a large nozzle (> 1/3 ID) and the spindle should not be longer than about 2 1/2" if you use this mixture.

Nozzleless Fuel (BP) is very hot fuel used for nozzleless rockets. Use 75/15/10 willow based BP or similar that has been ball milled in a pyro ball mill for at least 3.5 hours. Mix +3% mineral oil with lacquer thinner (about 1 part mineral oil to about 10 parts lacquer thinner) and then mix that with the BP and dry for 24 hours. Alternatively, and probably better, just mill in the 3% oil during the last 15 minutes of mill time. The BP is not granulated or made to pulverone, rather it is used as it comes from the ball mill. The mineral oil keeps the dust down and makes the BP soft and easily compacted. Hard grained BPs will often CATO because it is so difficult to eliminate the tiny faults in the compressed grain. Try using 2Fa as a nozzleless fuel sometime -- but make sure you retire sufficiently away from the rocket because it will pop. I've pressed 2Fa grains to 8000 pounds and they still had faults in them.

Note: Doc Barr was the pioneer on this, Stoddard and Steinberg continued his experiments. While Stoddard's instructions state that the composition must be slightly damp to chuff, I've found that it will chuff even when dried thoroughly - the Naphtha seems to make it chuff.  If no Naphtha is used, it seems to chuff much less.  I used a standard BP rocket spindle for these and fused them with fast Visco that had the tip dipped in NC lacquer and a bit of titanium. The reason for the hot fuse is that normal Visco (especially American) will not ignite the  core reliably. Another alternative is to press about 1/3 increment of whistle just above the nozzle. That always ignites them. The composition was pressed to about 3500 on the mix. It is important to use the same size magnalium each time. Different sizes affect both power and chuffing.

I used mineral oil instead of Vaseline.

1 lb rocket formula from Andy H. on rec.pyro

This is the formula I use for 1-lb rockets:

62 - KNO3
10 - Sulfur
15 - AF Charcoal (commercial)
2 - Dextrin
8 - 40-60 mesh pine
3 - Ball milled Kingsford (long-hanging sparks)

Mill together the nitrate, sulfur, air-float charcoal and dextrin
together for 3 hrs.  Screen in the additional charcoal, dampen, and
granulate through a 20 mesh screen.

Potassium Nitrate 54
Xylitol 27
Vitamin C 8 (editor's note: ascorbic acid)
Sulfur 7
Iron(III) Oxide, red 4

WARNING:  Xylitol is harmless for humans but dangerous for dogs. Because it is sweet, they will eat any residue left around. Be sure to clean up thoroughly if you have pets.

All ingredients should be milled together until fine and then melted and cast. The Xylitol melts at a low temperature; a cheap crock pot set on High is ideal.

Mixture is somewhat hygroscopic and should be allowed to cool overnight to harden. Keep in a sealed plastic bag until used.

 

Whistles

Strobes

Strobe Mix from Kent Z. 


I screen the following together a couple of times and then add 15% nitrocellulose with a little acetone to thin it out a little. I only get the mix wet enough to rice it thru a screen about the size of window screen. Spread out to dry.
My tooling is strobe tooling from Rich Wolter. I press about 1 3/4" of whistle before I press the strobe mix. I press both at about 6000 force pounds or 2000 psi on my hyd cylinder.

60 parts Ammonium Perchlorate 90 micron super fines from Firefox
15 parts Mag/Alum -325 mesh
10 parts Mag/Alum -200 mesh
15 parts Barium Sulfate
5 parts Pot Dichromate

Since I'm not using straight MAG I don't think you need the Pot Dichromate but my old formula called for Mag and I replaced it with Mag/Alum and never removed the Pot Dichromate and it seems to still work.

Strobe Mix from Ned G.

Making my strobe fuel is pretty simple. I use fine AP, 90 micron/down (about 200 mesh) and I've never noticed it or the Ba sulfate appearing damp. If I did, I'd dry them individually in a 220 degree oven.

The formula is:
.60 AP
.25 MgAl (200 mesh, which has some finer stuff)
.15 barium sulfate
+.05 pot dichromate
+.02 mineral oil

I simply mix the dry ingredients well, mix the mineral oil in enough Coleman fuel to get the mix good and damp, wet the fuel integrating the moisture well into the dry ingredients, and dry in a SS Pot in a larger SS pot filled with hot water (the McMurray method of drying).
The fuel will end up being like grayish/greenish sand, and consolidates rock hard when pressed.

The quality/type of the chems can make a big difference in this fuel. I just had to get some new Ba Sulfate, and I'll be interested in seeing if my next batch performs the same as the batches made with my old Ba sulfate...

BTW,
the dimensions of the spindle I'm using for my 2# strobes is:
3 3/8'' long
7/16'' bottom
5/16'' top

I press whistle halfway up it, then strobe to above the top of it 1/4'', then a half inch of whistle or red fuel, then a half inch clay bulkhead.

Comments: The GE silicone II is noted for having an ammonia-like odor, where the GE silicones smell more like vinegar. The dimensions of the rocket made with this propellant were 1 1/8 inch ID, with a 1/2 inch core.
Preparation: Mix the copper oxide, PVC and silicone first, in a plastic bag. Then mix in the ammonium perchlorate. The stuff is said to be somewhat crumbly, and presses well.

White strobe rocket propellant
Source: John Steinberg
Comments: Mix with NC and Acetone until it is blendable (1 kilo of comp and 4 to 5 ounces of NC binder). Dry until screenable then screen and dry overnight. Metals can be mixes of MgAl and Mg. Generally, the finer the MgAl or more fine Mg the faster the strobing. Try 300 mesh MgAl alone first to see results. If you don't have the finer MgAl or Mg then you will need to ball mill - this is a whole other safety issue and you should not do so without consulting with those who have done it. 20% MgAl (300 mesh) and 5% Mg (400 mesh atomized) causes the strobe to speed up until it is almost too fast. To press in a rocket, put in whistle mix until the spindle has less than 1 increment left to cover it. Cover it with strobe mix. Add more whistle or other things. This strobe mix is slow burning and won't provide a lot of lift so get the rocket off the ground with whistle or BP.

Nitrocellulose Lacquer Substitutes. 

NC Lacquer is quite expensive for what you get. You can purchase it in liquid form from some suppliers but it is usually much cheaper to buy the powdered form and mix it with acetone. Make a 25% solution by weight and then, from that, make a 10% working solution for your needs.

One good substitute is to buy a couple of six packs of Ping Pong balls and dissolve them in a 1/2 pint of acetone.  The resulting white mixture is a suitable substitute for NC and it is much cheaper.  I use a small paint can (a new one) and store the mixture in it when I'm done. If the liquid isn't thick enough - let it dry with the lid off for just a while (keep watch - it dries fast). If it is too thick, add a bit of acetone.  Some have complained that this solution isn't flammable enough - although I've certainly had no problems with it. It is definitely slower than real NC lacquer but it works fine.  Ping pong balls are not NC but are celluloid or plastic - don't use the plastic ones.  The right ping pong balls - the celluloid ones - will burn when lit with a match.

Another substitute is to buy some smokeless rifle powder and dissolve it in acetone. Smokeless powder is fairly pure nitrocellulose so you are dealing with the real McCoy when you use it. Be careful. I use both single base (pure NC) or double base (NC and  nitroglycerine bound together).  There is some argument that the double base can, under some very specific and unusual circumstances, separate out.  Just keep the mix tightly sealed and in a normal environment and you will be OK. Using acetone, make a thick mixture for your stock solution  and then dilute it for your different needs. Typically, 10% is the working solution.

Finally, some hobby chemical dealers sell NC powder. Buy that and mix your own NC Lacquer. It will be much, much cheaper than the liquid version.

Priming Liquid for Fuses A good priming liquid is made from the Ping Pong ball mixture (above) and about 1/2 BP. Use a film can for a container and mix thoroughly. Dip fuses in it followed by dipping the fuses in some loose meal. This will give you a great priming  medium - it will light the first time and every time. For added benefit, add 10% titanium powder to the meal before dipping. Once dry, it will light even the hardest to light rockets.

Star Compositions

Many of these are primed heavily (just to be sure).  BP and 10% Al outer, 75/25 for the next layer, 25/75 for the third. I mentioned Veline's prime before but I don't like it - it has many ingredients and it doesn't light the stars much better than a simple green meal mix (unmilled BP with hot charcoal - 75/15/10) +10 silicon, +10 dextrin.

Name: Red Organic (Bleser KP #1)
Source: David Bleser with comments

Composition:
70 Potassium Perchlorate
15 Strontium Carbonate (Creagan: works fine, easy enough to light if well primed)
10 Red Gum
4 Dextrin
1 Charcoal (airfloat)
+10 PVC (not Bleser - added in by Creagan to lengthen burn time - it also adds to the color)

Preparation:
Screen together well using a 60 mesh screen.

Dampen with water and cut or pump

Comments (borrowed from Alan Yates):

Substitution of the Strontium Carbonate with other metal carbonates for different colors works fairly well:

8 Sodium Bicarbonate: Yellow (Creagan: works as advertised - burns fairly quickly)
10 Calcium Carbonate: Orange (Creagan: works as advertised - nice Orange)
20 Barium Carbonate: Green (Creagan: did 20/10 Barium Carbonate and PVC. It is a bit washed out but I also did Veline's Green (with Parlon) and it seemed almost as pale - it is a bit harder to light so prime in three layers)

Bleser #1 burns quickly - almost too quickly. I added in +10 PVC to all the carbonate mixes and that slowed it down a bit and added to the colors. The picture above shows Bleser #1 with PVC with some sparkler stars and some strobes.

Notes: This one is hard to light! It also has a bit of ash. I had it covered with Veline's Prime and it just burnt the prime off leaving the star. Yeesh! However, this sucker does have a strong red color and it lasts a long time (when you get it lit). To be successful on ignition, I had to dust the bottom of the star board with lightly dampened Veline, then 50/50 Veline/composition, then 25/75, then pure composition, then press. I haven't tried it, but green meal with a little silicon or aluminum should work as a prime, too.

Falling Leaves (Chinese colored fuse):   

This is also made in green (see green stars below) and other colors. The red is fairly good and the fuse burns slowly. See Skylighter (and cannonfuse.com) for prices. It comes in 96 foot rolls. Cut off 1" pieces and prime one end with NC or Ping Pong Ball/Acetone mix and BP. 

The image above links to a demo that used a Black Cat Exploding Comet rocket as the lift platform. The Comets are cheaper Black Cats that can carry a star or two for testing. In this case, it carried a half dozen or more Falling Leaves. Click on the image to see the demo.

(SL - Probably Ned Gorski): Bill Kimbrough developed the recipe for this star a few years ago. I first saw it at Western Winterblast as a heading in one of Doc Barr's black powder rockets. It was and is spectacular. The effect is sort of like a rich silver twinkling kinda like a firefly, but surrounded by really red glowing embers. Not charcoal orange, but more red than that. The silver and red together are incredible. This is truly a noble star. You learn to make this one, and the girls will throw rocks at all the other boys. If all goes well, and everything burns up where it's sposed to, it is ''Fireflies on Cocaine,'' Otherwise the star is accurately called ''Flaming Shit Falls on You.''

A couple of notes. All parts are parts by weight; it doesn't matter what they add up to. The pine charcoal is critical. Without it, you ain't got the true Flaming Shit star.

''I like to take the [yellow] pine charcoal as it comes out of the yard grinder, and put it in the ball mill for 10 minutes. Sift out (remove) what doesn't fall through a window screen, and just use the mixed granulation of the charcoal--Better charcoal effect. I mostly roll mine with starpol as a binder, but I have made the formula into comets, stars, and even tried it in lance. Pump, cut or roll, works good for me, but never use starpol as the binder if it is to be the outside of a color change star, as it will surely cause a driven in (moisture) problem.''

Notes: This works ok - using more Parlon and no Dextrin and dissolving it in acetone seems to make it better but harder to light. Potassium perchlorates available in the U.S. have a good deal of foreign material in them - be sure you use a fairly pure perc else the color will be washed to white.

Lights easily, burns fast, good blue color.

Editor's note: This burns very fast. Cut them larger than you normally would - start with 1/2" for a 3" shell. I didn't use a prime since they seemed to grab fire very easily. No prime works but you might want to put on a thin one anyway just for protection of the chlorate surface-to-surface contact.

*Experimental attempt at making a blue lift for mines - the intent was to have a pure blue wall instead of getting interference from the orange sparks of 2FA.

Blue Stars with Paris Green from a post by Harry Conover on rec.pyrotechnics

Right out of Tenney Davis's book, here is the first one for a 'non-
electric' star comp.,

Potassium Chlorate                              48
Paris Green                                         18
Barium Nitrate                                      16
Dextrin                                                  3
Shellac                                                10

This comp produces very intensely color saturated blue stars, but
other than for test shells, I've never use it in preference to the
following composition, which for many years was mainstream fireworks
suppliers. The following formulation gained popularity when the cost
of powdered aluminum rapidly decreased. It is the 'blue electric
star'.  Davis lists this formulation, which he attributes to which he
attributes to Allen F. Clark.

Potassium Chlorate                             32
Aluminum                                            8
Paris Green                                        16
Dextrin                                                 2
Shellac                                                1

John Reilly's Blue (revisited)

After rereading Shimizu's  "Fireworks From A Physical
Standpoint" about a year ago, I dropped the PVC component in the mix
to only 5% and upped the chlorate and shellac.

Potassium Chlorate  62%
Black Copper Oxide  20
PVC                         5
Shellac                     9
Dextrine                    4

Chinese Blue (works best in small stars. Fades as you go bigger)

26 CuO
15 S
5 HCB
3 MgAl
5 Phenolic Resin (looking for substitute - maybe shellac or red gum and then wet with alcohol)

Purple (from Mike S. and others)


Potassium chlorate 24
Strontium carbonate 3-3/4
Copper oxychloride 2-1/2
Shellac 4
Hexachlorobenzene 2
Dextrine 1-1/2

"This gives a very clear pure lavender-purple color and is useful for making
wafers for married comets or for pillbox stars. If you don't have HCB, Saran might be the best substitute."

<from LK>

To speed this up but with less color saturation, use the following formula:

Purple Star (John Reilly)

This is a very nice chlorate "violet purple" Giovanni Forli sent me
some time ago and I like it a lot:

Potassium Chlorate      1 kilogram
Black Copper Oxide      220 gms.
PVC (very fine dust)      160 gms.
Strontium Carbonate     160 gms.
Red Gum                     100 gms.
Gum Arabic                   60 gms.

Damp with water and cut or roll.  Makes a fast burning,  easily lit
star.  I prime lighly with fine meal.  If you use Parlon instead of
PVC, it may change the color and burn slightly.  Also, this is more on
the blue side of "purple" than the red. Hardt also has some very good
compositions for purple using chlorate as well as perchlorate.

John Reilly.

Yes.  As Pyrotec said, gum arabic (acacia gum) can be substituted with
dextrine with little noticable difference.  I'd probably go to 4.0 or
4.5% dextrin though and adjust the red gum and pvc down 1% total.  You
can also make a nice blue chlorate star with this kind of mix:

Potassium Chlorate            60%
PVC                                  10%
Copper Oxide (black or red) 20%
Shellac                               6%   (red gum can be used also)
Dextrine                              4%

Damp w/water and cut or roll.  Light BP prime.  This isn't quite as
good as the KClO3/Paris Green,HCB, with stearine, or lactose and
shellac and dextrine but it's better than many in my opinion and lights
easily.

This is harder to light. Use green meal with +10 silicon and +10 dextrin. Two step prime it using 50/50 composition and meal/silicon for the first layer and then the meal/silicon mix for the second. Total prime is about 1/16".

Green star #1
Veline's Green and Bleser #1 (substituting Barium Carbonate and PVC (20/10) for the Strontium Carbonate) have been tried. Both are pale. Bleser #1 is explained under RED. Veline's green is:

This is probably the best substitute for green stars (as long as you buy the green Falling Leaves!). You don't have to worry about Barium compounds and it is fairly cheap. See Skylighter (and cannonfuse.com) for prices. It comes in 96 foot rolls. Cut off 1" pieces and prime one end with NC or Ping Pong Ball/Acetone mix and BP.

Comments: This one is easy enough to make and lights easily, too. I rolled it and primed it with three layers. It might be the best of the non-metallic greens I've tested so far and might qualify as a 'good enough' based on an 'ok' color and ease of ignition.

Notes from ukrocketry forum - a thread by BigG and others (see examples at:: http://www.ukrocketry.co.uk/forum/index.php?showtopic=480&st=45 )

Silver Star
kno3 : 60
Al spherical 200 mesh : 20
Sulfer : 14
Charcoal : 6
boric acid : 1
dextrin : 5

OR

Potassium Nitrate..........50
Sulphur..........................30
Aluminium......................20
Binder...........................+5
(Boric Acid.....................+1)

This composition makes a bright golden white. I think a true silver is probably reserved for barium nitrate or potassium perchlorate compositions, but this one is pleasing enough. For a binder I have used NC laquer (this was just added until the composition was cuttable, and was not exactly 5%) and dextrin (this was 5%). It will need an intermediate prime. In my experience, BP just burnt off, leaving it unignited.

Note that today, true "white stars" are credited for the metallic addition of Magnesium, or the organic (more common) inclusion of antimony trisulphide. You can also use Antinomy Metal powder. Formulas containing KNO3, Sulphur, and Antinomy will burn with a brilliant white much better then the white posted in the quote.

For Example:

Davis: (Creagan note - this is great and is listed at the top of this composition listing as a 'tried and true' formula)
KNO3: 62
Antinomy (III) sulphide: 17
Sulfur: 17
Dextrin: 3

Lancaster:
KNO3: 51
Sulfur: 18
GP: 15
Antimony Metal: 10
C (+150 mesh): 3
Dextrin: 3

Working many years with white formulas that utilize KN03, S and C (with or without AL), I had to redefine my understanding of “White" after using Davis formula.

White #1 (source: E. Hunkins)


Potassium Nitrate 61.53
Sulfer 20.51
Antimony Trisulfide 10.25
Meal 3.84
dextrin 3.87
 


White Antimony (Davis)


KNO3: 62
Antinomy (III) sulphide: 17
Sulfur: 17
Dextrin: 3

Comments: This is a nice star. It lights fairly easily (I used a good single coating of Veline's Prime), and it is not terribly expensive except for the antimony. The white is bright and pretty and it burns a medium amount of time.

White Strobe

Barium Nitrate .................51
Potassium Nitrate ............7
Sulfur ..............................19
Magnalium ......................18 (60 to 100 Mesh)
Dextrin ............................5

Comments: This seems to be a really easy star formula - it rolls exceptionally well and it definitely strobes. I primed it with three layers - but it lights ok - it's just that I have a hard time getting Barium Nitrate so the cost is pretty high and I want the stars to work. Click on the image above to see a test flight (using one of the high reliability 3/8" rockets with titanium delay - see rockets.html). The payload is two 5/16" strobe stars. The strobe stars almost hit ground - but not quite. They definitely last a good long time. I like 'em!

This is what we used for white in red-white-blue-report 3-break shells at the
All-American display at last year's PGI convention. It is a nice neutral white
and doesn't overpower the non-metal red and blue chlorate stars used in the
other breaks. It is only slightly modified (by adding dextrine in the modern
manner) from the composition used for white stars by Southby at Woolwich c. 1850.

Black Smoke Stars (Daylight Stars - Shimizu)

Potassium chlorate 44
Antimony 24
Napthalene 26
Dextrin 6

Use quickly else keep very tightly sealed. The Napthalene will evaporate if the stars are left in a device or left unsealed. The resultant star would be very sensitive. Always press these mixtures.

Another version by Ken Miller:

potassium chlorate - 60 %
napthalene, - 20 mesh (crushed flakes or mothballs are just fine) - 40%
antimony sulphide, dust - +4%

This mix was meant to be safer than the Shimizu version - and looks like it should be. Put this in a 1" tube with 1/2" nozzle or no nozzle. Light with a slight bit of comp and blackmatch.  Always press these mixtures.

An Easy Black/Gray Smoke (military formula) that produces volumes

Hydrochloroethane  45 (get it on eBay)
Zinc Oxide 45
Dark Aluminum 10

Prime using 50/50 smoke mix and meal then 100 meal.

Using dyes for smokes

First off, get good dyes - they are quite expensive so be prepared.  Here is an edited version of Ken Miller's comments about how to make good smoke cartridges

The basic formula is:

50% dye
30% KCLO3
20% sugar (confectioner's sugar works)

1) In a 2'' ID, we use, most commonly, a 3/4'' vent hole but 3/8'' would be a bit better.
2) The mix should be pressed. We use line pressures anywhere from 500 to 1100 psi on 2'' items. Not sure if that helps.
3) Any fine sugar sugar will work. For most items, we use confectioners dust. Ideal is anhydrous dextrose. Scam a free sample and ball mill.
4) Dampen yer smoke comp with NC/solvent as making pulverone. Press by hand into the bottom of the container and cover air-tight. Let sit 30 minutes. Granulate as pulverone. Granulate again. Let dry.

Now you have dust-free, fast/faster burning granules that are a joy to handle and easy to press. The additional mixing helps as the dye soaks into the chems.

If you really want to see the goodness, add a little 2-3% antimony sulfide to the mix. This was common during WWI and don't worry, it won't blow up in yer face. Just handle it as you would any friction sensitive mix, in other words, the same way you should be handling this stuff anyway. Do not add more than 3% antimony sulfide else the mix will become too energetic.

copper oxychloride to get your best version of aqua. My recommendation is somewhere around 2 to 2-1/2%. If you get to 3%, it likely will be a very expensive, but beautiful, blue.

Sometimes the aqua color is better using lactose, rather than gum, or half and half. The lactose burns cooler and that makes a better blue. For cutting, lactose often sticks to the knife. For rolling, it might be an advantage. I have not tried it with stearin.

Buttered Popcorn Glitter (Lloyd Sponenburgh)

Buttered Popcorn Glitter (posted once before but this is an update with comments from Lloyd... posted with permission)

5lb......Meal-D ....
6oz..sodium bicarbonate ....
9oz..antimony sulfide -325 mesh ....
8oz..Fine spheroidal Al (service X-fine) ....
6oz..dextrin

"Work the bicarb up and down by 1% amounts (1% of the bicarb amount) to increase or decrease the spritzel delay. It's simple, and will work properly with from 3% to 8.5% moisture when pressed; use JUST enough to make it cohere well at the pressure you're using.

For granulating, usually about 800-1000ml of water per 16lb batch works out just right. Linda named it ''Buttered Popcorn Glitter''. The spritzel puffs are roughly 3/4'' in diameter, and a rich buttery gold. I roll it into stars, press it into comets, and granulate it for pressing.

SOP is that all my formulae contain binders. Even with granulated comps, the binder makes it less dusty to press, and easier to granulate with less moisture -- and too much moisture is the enema .. ur... eneMY... of glitters. BTW... the amount of water used to granulate is usually considerably higher than that used to press. The 800ml is roughly 11%. But it doesn't seem to hurt the glitter, probably because I dry granulates rapidly in very shallow layers, preventing the sort of reactions that might cause them to deteriorate."

Editor's note: I asked Lloyd for permission to post this, he added the following:

Danny, that's fine. You might also add "(late comment -- as little as 200ml of water per 16lb batch works well for high-pressure pressing into comets, crossettes, etc.)

You might note for the readers that the batch represented is NOT a 16lb batch.

I bound these stars with home made flour paste, as made from the passfire site directions. I used enough paste to get the material so that it was stiff dough and shiny, but not runny. The stars burn about as fast as a chlorate color star, so you can cut them pretty large if you want. They light very easily with a flash bag provided you use a good amount of BP prime so that they have a little time to slow down before they ignite, insuring their continued burning.

Swisher Glitter (can be cut)

24 lbs. home made meal powder 384 oz, 65.3 %
4 lb. 8 oz. antimony sulphide 72 oz, 12.25 %
3 lb. Reynolds No. 120 atomized aluminum 48 oz, 8.1 %
1 lb. 8 oz. strontium carbonate 24 oz, 4 %
1 lb. 8 oz. sodium oxalate 24 oz, 4 %
2 lb. 4 oz. dextrine. 36 oz, 6.1 %

Sieve chemicals individually once through 40 mesh. Blend by hand and sieve 3 X through 20-mesh.
Aq. 3 lbs (48 / 588 = 8.1) to pump, 5 1/2 lbs (88 / 588 = 15) to cut

With a hobby mill, it is common to make 1000 grams of home made meal. If you do that then, the following are the ratios:

Meal - 1000 grams
Antimony Sulfide - 187 grams
Atomized Aluminum - 124 grams
Strontium Carbonate - 61.4 grams
Sodium Oxalate - 61.4 grams
Dextrin - 93.4 grams

Water to cut - 230 grams (Ed: water varies according the charcoal used - my test batch took over 350 grams)

Black powder meal 0.68 
Atomized aluminum 0.08 
Antimony trisulfide 0.08  
Sodium oxalate 0.11  
Dextrin 0.05 

Pumping is best. Use just enough water to bind in a star pump (5%?)

D1 Glitter

Source: Tom Rebenclau/Jack Drews and from Alan Yates

Composition:
53 Potassium Nitrate (corrected from 58 on some forums)
18 Sulfur
11 Charcoal (airfloat)
7 Aluminium (-325 mesh, spherical)
7 Sodium Bicarbonate
4 Dextrin

Preparation:
The composition designer suggests dampening with 6% plain water with 1 part of boric acid dissolved in it when pressing comets or pumping stars. It need not be ball milled if your components are already sufficiently fine, just screen together, moisten and granulate through a coarse sieve ready for pressing/pumping.

Comments 
I used it as delay for a 3/8 rocket.  It was about 50% slower than RP.   It didn't require priming for a light burst but priming would likely be necessary for a hard break..

 

Ofca's Gold Twinkler etc (source Passfire - Ned Gorski in response to questions about using  Meal-D):

Rob, in BAFN III, Bill Ofca has a Chrys 6 formula based on meal D. ''The Beautiful 4'' Spider Web Shell'' uses, in one of the formulae:

Meal D 10
KNO3 7.5
Airfloat 7.5
Sulfur 1
Dex 2

If you do some calculating, you'll see that this is a hot mix with the same proportions as Chrys 6.

My favorite Glitter is Ofca's Gold Twinkler, and as it's base I use a homemade granulated meal, which would probably work with commercial meal, too.

Meal 65
atom.al. 8
ant sulf 8
sod ox 11
dex 5
( 3 parts of boric acid are specified, but I don't use it.)

I like this one best if it is only very slightly dampened and then pumped as pumped stars or comets.

Have fun,

And another Ned quote: And, years ago, Charley Wilson turned me onto the fact that in many glitter-type comps, using a somewhat granulated BP as the base, to which the other chems are added, really changes and enhances the effect.

RED (SrN 50, MgAl-325 18, Par 16, RG 10, Dex 5)

 

RUBY (increase SrN to 62, reduce MgAl to 12, divide chlorine donor into equal parts of saran and parlon)

 

Emerald (exact same as ruby, sub BaN for SrN)

 

Note: to deepen a color, increase colorant oxidizer and reduce metal

 

BLUE (KP 66, CuO 14, Par 5, Saran 5, RG 10, Dex 5)

 

you can make mauve/magenta by adding SrN for some of the KP

 

ORANGE (SrN 42, MgAl 12, KP 10, Na Ox 10, Par 9, Sar 9, RG 8,

Dex 5)

 

you can vary color by ratio of SrN to NaOx

      (you can also put it on with a 10% solution of Gum Arabic instead of water or water/alcohol)

        Mix the first three ingredients thoroughly. Do not wet. All ingredients should be airfloat except the silicon. Additional benefit can be had by adding +10 diatomaceous earth or some 7F to get it 'bumpy' so it will take fire easily.

Gary Smith Parlon Stars (with permission)

Meant to be used with acetone or lacquer thinner as wetting agent

Above image courtesy of Lee C. Bussy.  All formulas by Gary Smith.

A summary of Gary's comments about the above chart: The formulas for the above stars are nominal.  The stars are NOT going to burn at exactly the same speed but they are close.  The silver will be the slowest but can be speeded up with finer MgAl. (Edit: I use 60 KCLO4 and 100-200 mesh MgAl)

The above stars are meant to be wetted with lacquer thinner or acetone and sliced through a 1/4" - 1/2" screen - depending on what size stars you want.  You can prime them after they have dried a short while.  Use a good thick prime.

Another way of making them is to roll the mix out between two pieces of plastic so they are a bit thinner than the ending star size you want.  Ned Gorski developed this technique. Here are his instructions:

As opposed to Gary who slices the stars with the screen, and then lets them dry prior to priming them, I dust the star patty with a version of Lloyd's pinball prime, on both sides of the patty, prior to slicing them through the screen.

Hot Igniter Star Prime:

0.71 pot perc
0.14 airfloat
0.09 redgum
0.06 magnalium

Then, pushing the star patty through the screen starts to embed the prime into the surface of the stars.

After the stars have been sliced, I tumble them in a tub, spritzing them with denatured alcohol to further take up the loose prime, and I put in another dose of the hot prime with some more spritzing.

Then I roll on a 50/50 mix of hot prime/BP prime (bound with redgum), using the same tub/spritzing method.

BP prime:

0.67 KNO3
0.14 airfloat
0.09 sulfur
0.05 magnalium
0.05 redgum

I then finish the priming by rolling on a layer/dose of the BP prime.

This ends up being a nice step-priming system, applied when the stars are fresh from the slicing.

The tumbling and priming produces stars which are almost spherical.

The total prime layers end up being about 1/16" thick.

I'm getting good ignition out of the stars, even in a hard-broken shell.

Gary and I have noticed that the acetone-parlon-bound stars seem to dry even more quickly with the primes applied, as opposed to drying without primes applied.

Other notes by Ned:

add .85 oz acetone to 5.25 oz star batch for 4'' shell (added .16 acetone..)
3.4 oz for 21 ounce batch

4T of each prime for a 5.25 oz batch
One 5 oz cup of each prime for a 21 oz batch

20-25 oz for a 6" shell

Veline Star Color System (as lifted from Skylighter newsletter: http://www.skylighter.com/skylighter_info_pages/article.asp?Item=8)

 Robert Veline created this system and intentionally put it in the public domain.  When you look at it, you can see that it uses very similar ingredients and proportions for many of the different colors, making this an extremely versatile color set:  you can create any color you want using only ten chemicals!

When you look at the part called "Now the Fun Stuff" you can even see how to mix an almost limitless palette of colors by mixing the different primary colors shown in the table.  A word to the wise:  These colors are well balanced in terms of color brightness and intensity.  So, Veline's colors seem to appear most pleasing when they are used with each other any given device (shell, mine, etc.).  Here's the original paper published by Veline, but formatted differently to fit our newsletter.

 A Few Notes About These Formulae

The numbers are in percent by weight.  The potassium perchlorate is a fine powder.  The Swedish stuff is what I used.  The parlon was Hercules brand, but Superchlon brand from Ishihara Co. Ltd. also works.  Nothing special about the red gum, just fine powder.  The best barium and strontium carbonates are obtained from Barium and Chemicals of Steubenville Ohio.  The calcium carbonate was -200 mesh 'Whiting'.  Copper carbonate may be used rather than black copper oxide without much change in performance.  I have tried finer more pure forms and found they have slowed the burn rate, and degraded the color...  Note that all of the proportions are the same for the different colors, the exception being the green.  The idea is to have as many characteristics, burn rate, brightness, flame size, color purity, and density of powder, common between the different powders, as is possible. While these formulas do not excel in any one characteristic, they are all part of a matched set.  The green:  I was unable to get a suitable green star for this family without using barium nitrate.  So, in order to compensate for the reduced oxidizing ability of the nitrate, a more energetic fuel mixture was used.

The directions are to make a gel with the nitrocellulose and solvent and use it to bind the mix. II really don't think the nitrate solvent is necessary and any ester of ketone could be used. The fuel / chlorine donor combo is interesting. They seem a little lighter in "parlon" than most US formulas and the vinsol/novolac blend would be lower in cost than red gum.

Go Getters
This section from an archived United Nuclear Page

Go Getters are essentially rocket propelled stars. They are used in an aerial shell or in the head
of a rocket and when ignited, they burn with a brilliant color (brilliant because the formulas all contain Magnesium  powder) and shoot across the sky. Lit on the ground or in the air, they will fly off in a random direction with their bright tail fire. The Magnesium in these formulas will not degrade because of the unique solvent used.

Comments:

The chemicals are first finely powered (if they are lumpy or coarse crystals) then mixed well together.
For the next step, you'll need a small squeeze bottle, similar to those plastic squeeze ketchup bottles you find in a restaurant. Take the mixed formula and slowly add Acetone (while mixing) until it has the consistency of pancake batter. The Acetone will melt the Parlon in the mixture making it plastic & gooey. Be sure to test the squeeze bottle you are going to use first by putting some Acetone in it. Acetone will also melt many plastics, so make sure your squeeze bottle isn't going to melt too. The melted Parlon in the mixtures will also coat the Magnesium Powder and prevent it from degrading. The Parlon here not only binds the mixture together, but it boosts the color of the flame by providing Chlorine to the burning mixture.

Next, stand some M-80 tubes up end on a sheet of Aluminum Foil. Pump the mixture into them until they are about 80% full. If they are to be used in shells or rocket heads, insert a piece of Black Match (that's Quickmatch with the outside paper removed) all the way to the bottom, leaving about 1" sticking out the top. You can also insert a piece of Visco Safety Fuse, but the ignition delay will be longer. Let them dry for 3 to 4 days. 

When lit, they will burn with a brilliant colored flame and shoot off in a random direction. Be very careful if you light one on the ground. It can launch in an unpredictable direction... and with its burning hot Magnesium flame, ignite whatever it lands on

 

 


Dragon's Eggs

from Passfire Discussion On How to Prime

(prime with melted paraffin wax)

the formula is under crackling microstars, credited to David Trimmel, I believe.

bismuth trioxide 37.5%
copper(II) oxide 37.5%
magnalium 25%

I use bismuth subcarbonate instead of bismuth trioxide, 1:1

Comments from posting (not LK comments): He says to bind with Winchester 231 double base(?) and amyl acetate. I used no amyl acetate, only 231 dissolved in acetone to spray consistency. They are impressive. I coated some with wax before priming, and they are even louder. I primed with KClO4 70%, MgAl 20%, red gum 10% (inner prime), then a hot BP outer prime. They seem to perform best with fairly thick primes, so they do tend to get bigger than you'd expect. But LOUD !

Editor's note: I have not had to use wax to get good results with this formula. Make sure that the layers of material are bound with different methods. The egg uses NC, so use a water binding for the prime. Use an NC or acetone/parlon binding for anything on top of the egg prime.

A web page has been made for this. See the index.

Dragon's Eggs from rec.pyro (Lloyd Sponenburgh Method)

A web page has been made from this. See the index.

Here's a re-preach from an earlier question:

--------------------------------------------------
The formula is no secret.  The real secret to getting good crackle is just getting enough NC in the mix.  You'll understand lower down in this email.

This formula has been circulating on the internet for years:

71  Bismuth trioxide
14  Black copper oxide
10  Magnalium (see notes)
 5  fine atomized aluminum (-300 mesh, like Service Chemical "X-Fine")

The magnalium for "regular" crackle is 200-mesh.  The coarser the magnalium mesh, the longer the delay between ignition and explosion.   At 80-mesh, it's about three seconds, and pieces as large as ¼" will explode in a single explosion.  The finer the magnalium, the smaller the pieces must be.  At 200-mesh, 1/8" dia. stars are about as large as you can make them.  Otherwise, they just spall small chunks, and
the body remains un-reacted.

The mixture is screened well, then mixed into a wet, sticky dough with 10% w/v nitrocellulose lacquer made from double-base powder (like Green Dot or Blue Dot or Bullseye shotshell powder).

There's a secret to making the lacquer that I've published over and over, and folks STILL think it takes a couple of days to make.  In reality, it takes about 30-minutes.

Measure out the acetone in a vessel at least four times larger than the volume you're working with.  I use a deep stainless steel mixing bowl from a kitchen mixer.  With a kitchen whisk in your strong hand, and the weighed NC powder in the other, start slowly but uniformly pouring the powder into the acetone while you whisk your arm off.  Mix FAST, and don't stop until the whole mass thickens up to about the consistency of heavy cream.  Work lumps down off the sides of the bowl as you go.  Don't _ever_ let any undissolved powder settle to the bottom.

Now, cover the bowl and let it sit for about 30 minutes.  Come back and whisk again for about three or four minutes, and your lacquer is ready.  You can ignore any "soft lumps"; they'll dissolve during the
kneading process. In another large, shallow bowl, "crater" your crackle mix, and start adding NC lacquer, a little at a time - just like making bread dough.

Knead it thoroughly.  At first, it will become "mealy" like making pie dough.  As you add more NC, it will become more and more dough-like.   Knead it until it's perfectly smooth and homogenous, and quite a bit
on the sticky side of too wet.  It should end up almost impossible to knead properly any more because it's too sticky to handle.  It should be about the consistency of a very thick batter, rather than a dough.

This is hard work.  Wear stout rubber gloves.  Scrape your gloves down into the wet mix to get the dried chunks back into the mass.  I know this might sound silly, but DON'T allow sweat to drip into the dough…
don't.  (you will be sweating)

It's important to the loudness of the crackle to get enough NC in there.  If the dough ends up too sticky to handle, that's OK… Just mush it out flat and let it dry a little.  As it dries (and it dries pretty fast) it will lose its stickyness.  Keep working the wet mass until it returns to the consistency of a stiff dough.

Once the dough is back to the right consistency, more "push" than "scrape" it through standard ¼" hardware cloth onto trays lined with paper.  You'll get ¼" "worms" about two inches long or less.  Don't
layer them more than a couple deep, or they'll all stick together.  If they do, let them dry a little, knead them back into a lump, and repeat.

Let them dry slowly in the shade without molesting them JUST until you can "diaper" the mass without having the worms stick to one-another.   The goal is to get them partially dry, but not so dry you cannot
further process them for smaller grains.

Now, working with a small amount at a time, push these worms through 6-mesh screening.  6-mesh gives 1/8" stars.  Especially now, don't layer the mass; you must keep the stars from adhering to one-another.

As they dry a little more (the "knack" part comes now), put them back in the 6-mesh screen, and gently ROLL them back through the screen with the flat of your gloved palm.  Avoid scraping or pushing straight
down.  What you're doing is basically rounding off the chunks and forcing them to size in one operation.

Let these stars dry thoroughly, occasionally diapering the mass to get damp ones to the surface.   In the sun, they should dry completely in an hour or so.  You should detect no acetone odor, but you will smell
a "sharp" odor from the nitroglycerine in the NC lacquer.

Finally, re-screen the entire mass to remove chunks larger than 6- mesh, and sift out any "fines" smaller than about 10-mesh.  The big pieces and the fines may be re-processed later simply by adding acetone and re-kneading.  You can make really small stars for crackling gerbs with the -10+20 pieces, if you wish.

Now, prime them.  Make up a saturated solution of potassium dichromate as your rolling solvent. DO NOT USE plain water - the stars will react with water, and can actually ignite from the heat.

Start a fairly large mass of the dried stars rolling in your star roller.  They must tumble freely.  They're so heavy that a small mass will just slip around in the drum.  In fact, they may not tumble at all until you start to dampen them with solvent (gives a little "bite" on the surface of the drum).

Wet them with the solvent until they glisten, but still tumble freely.   Lay on a layer of simple rough-mix powder (75/15/10 +7% dextrin). Do not mill this… you want it coarse; just mix it by screening repeatedly
through 20-mesh.  Just like star rolling, add dry mix until they'll not take up any more, but try to keep the layer smooth, without excess dry mix in the mass.  

Do only a couple of layers.  The goal is NOT to build them up in size, but just to evenly coat all surfaces of each grain.  There shouldn't be any grey crackle showing, but the grains should be only marginally
larger than when you started.  Finish up with a large excess of dry powder to make the grains' surfaces "dusty" for easier ignition.   Uniform ignition over the entire surface of the star is part of the secret to getting it LOUD.

Dry these again in the sun and gently sift out the excess priming mix, and you're done - with straight crackle.

Add up to 10% by weight of fine titanium sponge or flake to the original mixture (60-100 mesh) to get the "brocade" burst effect.

Around five pounds per batch is about as much as one person can handle comfortably at one time.

Although this sounds like more work than making cut stars, it's lots faster, and turns out a good product.  Even for cut stars, you have to do everything but the screening phases, and cutting uniform 1/8" stars
is difficult.

Once you've made five _finished_ pounds of these, call me up, and we'll get you some therapy for your arms.

Let me know when you've achieved a forty pound day!

And yet another formula.  If you start using the dragon's eggs formula and aren't quite satisfied, try adding a bit of dark aluminum to the mix.  Lloyd has often pointed out the the aluminum content can affect the price of eggs. ;-}

Crackling Flowers (source Harold Plumber on Passfire)

The secret of success is to prepare the smoldering composition in such a way that it creates a glowing melt that protects the Ti flakes from reacting with the atmospheric oxygen. When the heat from the melt ignites the crackling core, the molten star bursts and the hot Ti flakes ignites in the air, creating the Dandelion ball.

I have no specific formulas for this type of effect, but I do know that smoldering compositions are easily made from overloading glitter compositions with sulfur!''

Since then, I have met and spoke to a Japanese pyrotechnist who explained the effect in more detail:

The Japanese call them Crackling Flower Stars to distinguish them from ordinary Crackling Stars.

The star contains a crackling star core made from either a traditional lead based composition:

46 Lead Tetroxide
16 Lead Dioxide
16 Copper oxide
22 Magnalium (200 mesh)

or a bismuth based composition:

30 Bismuth Oxide
40 Copper Oxide
30 Magnalium

In both cases the crackling core compositions are wetted with NC lacquer and granulated through a 8 mesh sieve twice. After drying the bigger granules are separated from the finer on a 10 mesh sieve and the result should be granules about 2-2.5 mm.

The cores are then coated with a special prime:

70 Potassium perchlorate
12 Red Gum
5 Potassium Dichromate
3 Magnalium (200 mesh)
10 Silicon powder (200 mesh)

A titanium spark composition is then added by rolling the crackling cores with the following composition (NC lacquer is used as binding system):

34 Potassium nitrate
6 Sulphur
5 Antimony trisulphide
15 Pine Charcoal
20 Titanium
20 Resin

The resin was not specified but I guess it is red gum or some synthetic resin of phenolic kind.

Everything above was published in the proceedings of the 8th International Symposium on Fireworks!

Edit:
I forgot to add that Mr. Sashimura believed that substituting the Ti for coarse MgAl could produce an even better and louder effect since coarse particles of MgAl burn with a crackling noise of their own!

Slow Flash Discussion

Slow flash is used for break for shells.  Ned G. uses 2-1-1 (potassium nitrate, sulfur, dark aluminum) dusted onto rice hulls. Depending on the kind of dark aluminum, the slow flash can be quite fast and might be too harsh.  For instance, Eckhart 5413H makes a very hot slow flash which is almost unusable as a breaking charge except on small shells.

An alternative was offered by Eric H. which tempers the flash and gives good ignitability:

Here is the formula we used for production for many years.

Potassium Nitrate 31
Barium Nitrate 31
Aluminum 19
Sulfur 12
Antimony Trisulfide 7

Robert W. also cited using Ned G.'s formula and Eckhart 5413H but using 1/2 barium nitrate and 1/2 potassium nitrate.

Potassium Hydrogen Terepthalate

To make potassium hydrogen terepthalate: dissolve 6.9 grams of potassium carbonate in water. Add 16.6g of terephthalic acid and let it react. Filter.
