Description
Naturally occurring mineral composed of Potassium nitrate. Also known as saltpeter, niter has thin, shiny translucent crystals. It usually occurs as Efflorescence on the surface of soils in arid regions. Large quantities of niter have been found in Spain, Italy, Egypt, Arabia, India, Russia, and the United States. Niter was used during the Civil War as a component in Gunpowder. It is now used in the manufacture of Glass, matches, explosives, and fertilizers.
