Brief Facts About GunPowder:
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.
