History of Gunpowder in Timeline
Gunpowder, also known as black powder, is the oldest known chemical explosive. It is composed of sulfur and carbon, which serve as fuels, and potassium nitrate (saltpeter), which acts as an oxidizer. Gunpowder has been extensively utilized as a propellant in various applications, such as firearms, artillery, rocketry, and pyrotechnics. It has also been employed as a blasting agent in quarrying, mining, and construction projects like pipelines, tunnels, and roads.
