Painting showing gunpowder bombs


A rapidly burning material used as a propellant in guns and rifles. Gunpowder was invented in China in the 9th century. It is composed of a mixture of potassium nitrate (75 %), sulfur (10 %), and charcoal (15 %). Gunpowder burns inefficiently leaving copious residues of soot and alkaline potassium hydroxides. If left uncleaned after firing, the residues will rapidly degrade the barrel.
