Combustion is a fast, heat-releasing oxidation of a fuel by an oxidiser, usually the oxygen in the air, that gives off both heat and light. It is what powers fire, explosives and rocket engines.
Appearances in works
Black Powder
Roughly 75% saltpeter, 15% charcoal, 10% sulfur. What each ingredient does, why it deflagrates instead of detonating, and the sulfur mistake in Dr Stone.
Dynamite
Alfred Nobel, in 1867: soaked into diatomaceous earth, nitroglycerin became safe to carry. Why that works, what it changed, and the dynamite in Dr Stone.
