Gunpowder, any of several low-explosive mixtures used as propelling charges in guns and as blasting agents. The first such explosive was black powder—a mixture of saltpeter (potassium nitrate), sulfur, and charcoal—which is thought to have originated in China, where it was being used in fireworks by the 10th century.
