Clearly you are safety conscious and wise enough to visit this forum before making it but can I urge you to try making some other compositions first? If indeed this is your first which your original question suggests. It's just that flash is pretty high risk for the less experienced. And it gives fireworks a bit of a bad rep if tested in a built up area.

This isn't my first foray into pyrotechnics (or chemistry) and I've made flash more times than I care to recall. I've usually bought everything already milled and "ready to go" as it were. Just wanted to double check something that wasn't on the MSDS.

I'd rather ask a stupid question and get an answer - than risk an injury. (Remember, there are no stupid questions, only stupid people!) ^_^

Using it to make flash powder to use towards the end of a BP rocket to make a small report. Hence my posting here.

Rather than create a new topic for a thread on the subject, I thought I'd revive this one if nobody mines.

I've bought some Potassium Perchlorate and it's very course, and after reading the MSDS (http://www.sciencela...?msdsId=9924687) it doesn't specifically say yay or nay to it's sensitivity to crushing/grinding.

Is it safe to grind this in a pestle/mortar? (Alone, obviously. Not mixed with anything)
