Description
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.
