So- Ive seen lots of CIA, modified CIA, methods. Cooking the K,C,and S together; precip with cold alcohol; but right now you cant get isopropyl for love or money. Ive been wondering.. what do you think about putting the K,C,and S with miinimal water in SS pressure cooker till it gets to 15psi and most of the air is gone, then hitting the pressure cooker with a stream of very cold water. It cools very quickly, even creates a little vacuum. My question is - would the mix deflagrate in the pressure cooker? Scared I might be making a bomb. Or leave the top off, get it boiling, take off heat, seal the top , and immediately hit it with cold water? What do you think? That would keep the cold water off of the mix as it is rapidly cooled.
I'm new here. I don't fully understand what your trying to make, but it sounds dangerous to be heating up this mixture.

Cia powder isn't really a reliable, long term useful practice. There's a reason why the proper name includes " improvised "
Look for denatured alcohol in hardware stores.
If you want to make good BP. You need good charcoal. And, preferably an optimized ball mill, with lead media.

Anyway, back to the original topic. I have made a white/gray star with 60% potassium nitrate, 30% sulfur, 10% charcoal, + 5% dextrin. It worked best for me when doing cut stars, but you can try to pump them also. All the BP based stars I made would break apart when pumped, but I don't think I added enough water to activate the dextrin. The pumped stars worked okay in mines but they would break up in shells.
