Question about flash powders and their "safety".
I have recently tried mixing two flashpowders, specifically using KNO3 and Sr(NO3)2 with magnesium dust as fuel. While doing research into their safety, I also (among other things) asked AI, which insisted that these mixes are highly sensitive to friction and static electricity, and that the only way to safely mix them would be using special static proof paper and stuff. Now I'm used to AI being a bit stupid, but I still wanted to ask if anyone has experience with these sort of mixtures and their sensitivity.
So far, I've handled small quantities (under 10 grams) of the stuff, using normal paper to mix them (not thoroughly mind you), and got pretty good results. I'd love to mix them more thoroughly, but for that I want to be sure that it's not gonna blow up in my face.
