How do you extract potassium nitrate from fertilizer? Answered
I have been fiddling around with a few homemade fireworks, and I have found a certain want for potassium nitrate, something which works very well in fireworks. Does anyone know how to remove this from my everyday garden fertilizer? I heard it can be done, I just dont know how... Thanks! P.S. I dont need any warnings about using fireworks, I am very sensible.
