Flash Powder
All of the powders should be ground up into a very fine powder, about 400 mesh or better. Common household flour is about 400 mesh. You can sometimes buy powdered aluminum or other chemicals at 600 mesh. This stuff is awesome for flash powder!
The mixture of any chlorate with phosphorus or sulfur is extremely sensitive to friction and percussion and explodes with great violence. Chlorate explosives must not be stored together with ammonium nitrate explosives, since ammonium chlorate which is formed when these two substances touch explodes, taking both mixtures of flash powder with it.
When mixing chlorate explosives, crush all of the chemicals separately. Sift the oxidizer through a piece of screen wire to break up the material into small pieces. Then sif the other chemicals if they need it. Mix all the chemicas together and finish up by sifting them through a piece of fine wire screen or shaking them in a Zip-Loc bag. Do not use this kind of mixing when the mixture is sensitive to friction, impact, or static electricity.
Formula one:
- 2 ounces of Potassium Perchlorate
- 1 ounce of 600 mesh Aluminum Powder
This formula is one of the best. It produces a very, very, extremely lound explosion. Easy to ignite with a fuse, it is not moisture absorbent, not very sensitive to impact or friction. Sodium chlorate or Potassium chlorate can be used instead of potassium perchlorate but it becomes very sensitive to friction and impact.
Four ounces of this stuff equals one stick of dynamite.
Formula two:
- 2 ounces of Potassium Perchlorate
- 1 ounce of 400 mesh Aluminum Powder
This formula is almost as good as formula one. This is what most firecrackers, M-80s and other fireworks are made of.
Formula three:
- 3 ounces of Barium Nitrate
- 3 ounces of Potassium Perchlorate
- 4 ounces of 400 mesh Aluminum Powder
This formula produces a very bright flash. It used to be used for the flash boxes for olden day box cameras you see in the old movies. That T-stick the photographer holds up is filled with this stuff.
Formula four:
- 2 ounces of Potassium Perchlorate
- 1 ounce of Sulfur
- 1 ounce of 400 mesh Aluminum Powder
This formula is not very impact or friction sensitive. It produces a very, very loud explosion.
Formula five:
- 2 ounces of Sodium Chlorate
- 1 ounce of Sulfur
- 1 ounce of 400 mesh Aluminum Powder
This formula is very moisture absorbent but it is very imact and friction sensitive. Not so much flash as noise is put out by it.
Formula six:
- 2 ounces of Potassium Chlorate
- 1 ounce of Sulfur
- 1 ounce of 400 mesh Aluminum Powder
This formula is used in the manufacture of cap gun caps, so naturally it is very impact sensitive. Watch out, because it could blow up at any time when making it. Only make small amounts at a time, so if it blows up, it won't take you with it.
Formula seven:
- 6.7 ounces of Potassium Chlorate
- 2.7 ounces of Red Phosphorus
- 0.3 ounce of Sulfur
- 0.3 ounce of Calcium Carbonate
This formula is very, very, extremely sensitive to impact, friction, and even electricity. It is amazingly dangerous!! It will ignite even when wet. Stay as far away from it as possible, especially when making it.
Formula eight:
- 2 ounces of Potassium Permaganate
- 1 ounce of Sulfur
- 1 ounce of 400 mesh Aluminum Powder
This formula is slightly impact sensitive, so be careful when making it. I love it because it ignites automatically when it gets wet. Dump some water on it or leave it out when it's raining and kablooey! This stuff has endless uses.
Formula nine:
- 7.5 ounces of Potassium Chlorate
- 1.5 ounces of Charcoal Dust
- 1 ounce of Sulfur
This formula produces a very small explosion when ignited in the open, but when put in a strong container, can really blow things apart with lots of noise. It is impact and friction sensitive, so watch out.
Formula ten:
- 6 ounces of Potassium Chlorate
- 3 ounces of Animony sulfide
- 1 ounce of Sulfur
Watch it, because this formula and the ones following have not been tested and could be highly volatile. Only make these if you are into pain.
Formula eleven:
- 7.5 ounces of Sodium Chlorate
- 1.5 ounce of Charcoal Dust
- 1 ounce of Sulfur
Formula twelve:
- 7.5 ounces of Potassium Chlorate
- 2.2 ounces of Gallic Acid
- 0.3 ounce of Red Gum
