Saltpeter is the common name used for several different chemical compounds, specifically for potassium nitrate and sodium nitrate. Potassium nitrate is commonly used in gunpowder, and sodium nitrate is found in fertilizers and explosives.
Salt is also used for countless other purposes, such as removing snow and ice from roads, softening water, preserving food, and stabilizing soils for construction. The earliest humans obtained their salt from natural salt concentrations, called licks, and from meat.
