What are the components of black powder?
Black powder is a low explosive, composed essentially of a mixture of potassium nitrate or sodium nitrate, charcoal, and sulfur. It is hydroscopic and subject to rapid deterioration when exposed to moisture. It is also one of the most dangerous explosives to handle because of the ease with which it is ignited by heat, friction, or spark. Although the use of black powder as a propellant and as a projectile bursting charge has ceased, it remains an explosive that will be encountered in ammunition and ammunition components.
