He could go the opposite route: Take advantage of the much (13g vs. 87g/100ml @ 0C) lower solubility of KNO3 in cold water, dissolving the sodium salt out. 3 steps in big buckets could give some pounds of say 98% purity.

Is that still too hygroscopic? I know it is not good for coloured comps, since the sodium yellow will overpower most other colours. But for BP, lift, candle comp etc it might be OK, especially for a beginner with a small budget.
The best solvent: Phenylacetone. Even solves a chemist's budget problems.

Okey, I have a theory, but I dont know if it would work. I wanna take this potassium sulfate and buy some pure N and mix these two. Would it be potassium nitrate? Or could I use this for smoke bombs?

I think its a sickness to ask everything out before testing. :huh: :blink: :D

uhhhh....that wouldn't work. The air we breathe is ~75% Nitrogen so if there was any way that it would work, it would have already been reacted by now. I think you should just buy some potassium nitrate, it's one of the cheapest chems for pyro out there.

Also think, sulfir is more reactive than Nitrogen, aswell as that N is a gas, so N will not displace S. Not a very good Idea, if you want to make KNO3 from K2SO4 do the nitrate fertilizer set up. Also K2SO4 will not work in smoke b0mbz, it is a high temp oxidizer so it can be used in SOME fl*sh powder.

I seem to have learned a lot from this forum :D.
