An interesting formula found in an old book.
Bright "Z" composition[]
It is a nitrate based composition wich employs bronce Al and atomized Al in order to get nice sparks and a bright white light.
This composition can be pumped, cutted or rolled and primed with pulverone.
| Bright "Z" white composition | Percentages % |
|---|---|
| Potassium nitrate (fine powder) | 47 % |
| Brigth aluminum (flake) | 14 % |
| Aluminum (atomized spherical -325 mesh) |
24% |
| Sulphur | 9% |
| Dextrin | 6% |
| Boric acid | +1% |
Mixing and cutting[]
Screen all the chemicals by separate and mix them by hand in a bucket, use latex gloves. after that screen the mix 1 or 2 times but if the chemicals are really fine this would not be necessary.
After the mix is ready a 1% solution of boric acid is added to get the right consistency. Try to use as little of water as posible until you get a dough consistency.
This takes about 2-3 days to fully dry, you can prime it with plain Black powder and its ready to be used as filler in shells, candles and whatever you want.
This is a batch of stars being primed and cutted, some of them get crushed but those will be a great filler in any gerb.
