Gunpowder
Gunpowder, also known since the late 19th century as black powder, was the first chemical explosive and the only one known until the mid-1800s. It is a mixture of sulfur, charcoal, and potassium nitrate (saltpetre)—with the sulfur and charcoal acting as fuels, while the saltpeter works as an oxidizer. Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a pyrotechnic composition in fireworks.

Famous quotes containing the word gunpowder:
“And there were present
the Picninnies,
and the Jobillies,
and the Garyulies,
and the great Panjandrum himself,
with the little round button at top;
and they all fell to playing the game
of catch-as-catch-can,
till the gunpowder ran out at the heels of their boots.”
—Samuel Foote (1720–1777)
“Genius as an explosive power beats gunpowder hollow; and if knowledge, which should give that power guidance, is wanting, the chances are not small that the rocket will simply run amuck among friends and foes.”
—Thomas Henry Huxley (1825–95)
