Ok, Ive been sussing out some saltpeter and in a different post I came across this "potassium nitrate fertiliser".
This is the link:

I'm not sure about "Soluble Potash (K2O) 46%". Does anyone know if this saltpeter is viable for use in BP?

Hey all.

I'm building my own ball mill however i'm not sure where i can get the lead non-sparking balls from in Australia. If anyone could point me in the right direction, it would be greatly appreciated.

Cheers
