i found a place here in aus that sells potassium nitrate in powder or granul form. I asked them how pure it was and they said 13% nitrogen 38% potassium.

 

Im wondering if that would require purification or if it usable how it is. I searched google but i was unsure so i thought i was ask here before i brought it. It comes in a 25kg bag and costs 32$ Aud

 

cheers

That will be fine for pyro use, wont need purification and the price isn't bad ether. Get it in powder form as it will be easier to work with
