I am working on upping what i deal with in pyrotechnics and before i
move onto good flash (perchlorate) i have been testing a lot slower
burn rate flash. I used to just make my own aluminum powder in a ball
mill and that worked just fine but production as you might have
guessed was slow (i used aluminum foil). so now i ordered aluminum
powder online and it was "rocket grade atomized aluminum powder". i
tested it and in order to light it i would have to put something like
bp that would burn hot enough to ignite it because my torch lighter
didn't work. now i didn't have this problem with my Al foil powder but
now suddenly when i order what should be better it won't even light
with a torch lighter. the Al i ordered was 300-325 mesh. could someone
give me some advice on what i can do so i can light it without using
bp. i know that the kno3 and sulfur are not the problem because i made
a few grams using the al foil one and next to it tried the rocket
grade stuff and the al foil one lit with a torch lighter easily. The
ratios i have tried are 5:3:2, 5:2:3 KNO3,S,Al
any help is much appreciated.
