Gunpowder \Gun"pow`der\, n. (Chem.)
A black, granular, explosive substance, consisting of an
intimate mechanical mixture of saltpeter, charcoal, and
sulphur. It is used in gunnery and blasting.

Note: Gunpowder consists of from 70 to 80 per cent of niter,
with 10 to 15 per cent of each of the other
ingredients. Its explosive energy is due to the fact
that it contains the necessary amount of oxygen for its
own combustion, and liberates gases (chiefly nitrogen
and carbon dioxide), which occupy a thousand or fifteen
hundred times more space than the powder which
generated them.

is known in England as {Guy Fawkes Day}.
