gunpowder
n 1: a mixture of potassium nitrate, charcoal, and sulfur in a
75:15:10 ratio which is used in gunnery, time fuses, and

Gunpowder \Gun"pow`der\ (g[u^]n"pou`d[~e]r), 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.
[1913 Webster]

Note: Gunpowder consists of from 70 to 80 per cent of
potassium nitraate (niter, saltpeter), 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.
[1913 Webster]

{Gunpowder pile driver}, a pile driver, the hammer of which
is thrown up by the explosion of gunpowder.

{Gunpowder plot} (Eng. Hist.), a plot to destroy the King,
Lords, and Commons, in revenge for the penal laws against
Catholics. As Guy Fawkes, the agent of the conspirators,
was about to fire the mine, which was placed under the
House of Lords, he was seized, Nov. 5, 1605. Hence, Nov. 5
is known in England as

{Guy Fawkes Day}.

{Gunpowder tea}, a species of fine green tea, each leaf of
which is rolled into a small ball or pellet.
[1913 Webster]


Explosive \Ex*plo"sive\, n.
1. An explosive agent; a compound or mixture susceptible of a
rapid chemical reaction, as {gunpowder}, {TNT},
{dynamite}, or {nitro-glycerine}.
[1913 Webster PJC]

2. A sound produced by an explosive impulse of the breath;
(Phonetics) one of consonants p, b, t, d, k, g, which are
sounded with a sort of explosive power of voice.

Note: [See Guide to Pronunciation, [root] 155-7, 184.]
[1913 Webster]
