An interesting formula found in an old book.

|Bright "Z" white composition||Percentages %|
|Potassium nitrate (fine powder)||47 %|
|Brigth aluminum (flake)||14 %|
|Aluminum (atomized spherical -325 mesh)||
Mixing and cuttingEdit
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.
