It might interest you that according to J. Donner's "Professional's Guide to Pyrotechnics" there are three official formulas for the original mix of M-80 powder.
1) KClO4 (64%), Al (22.5%), S (10%), Sb2S3 (3.5%)
2) KClO4 (66%), Al (17%), Sb2S3 (17%)
3) KClO4 (66%), Al (17%), S (8.5%), Sb2S3 (8.5%)
The author of the book refers to Joseph H. McClain, Pyrotechnics (Philadelphia: Franklin Institute Press, 1980) 122 for this information.

Are any of Donner's 3 formulas you list faster than the comp you lit in the vid???

@theitalian556 Thank you sir.

@Khalastas Sulfur, yes pardon my spelling mistake.However, adding sulfur in MOST flash mixes makes the flash more unstable, especially with KCL03! Feel free to look it up if you wish.
-
Sulfur, and I may be wrong, but it is generally used to reduce ignition temperature and therefore technically sensitize it.

KClO4/Al = 65,82% / 34,18% (OB=0%)
Perfect ratio, oxygen balance is zero, fastest mixture

@NeoBojownik Thanks, I'll try that ratio when I can but in the mean time I’ll write it down. It's going to be a while before I get back into pyro. Right now I have other priorities.

what's the difference of al mg and mg/al and what's the best?
alansk896 9 months ago
@alansk896 In this case there is no difference. 66% MgAl will do instead of measuring out 33% Mg and 33% Al.
However if the metal ratio's were different say for ex. 15% Mg and 51% Al, then there would be a difference.
