Potassium Nitrate, technical grade crystals, 1 lb. Unit

If you're making your own black powder you'll need a large amount of potassium nitrate as it makes up 75% of your black powder. A lot of pyrotechnic formulations use black powder as it's base including primes, glitters and many spark-producing formulations. 

This particular potassium nitrate works great for ball milled or screened black powder.
