Potassium Nitrate Safety

Potassium nitrate is a chemical compound made up of potassium, oxygen and nitrogen. Historically the chemical was used to make gunpowder, however, it was replaced by chemicals that did not absorb moisture as quickly or leave as much residue in the gun barrel. Today potassium nitrate is used in fertilizers, fireworks and grenade fuses.
