Fulminating Mercury
Dissolve 100 grains of mercury by heat, in an ounce and a half of
nitric acid. This solution being poured cold upon two measured ounces
of alcohol previously introduced into any convenient glass vessel, a
moderate heat is to be applied, till effervescence is excited. A white
fume then begins to appear on the surface of the liquor, and the
powder will be gradually precipitated when the action ceases. The
precipitate is to be immediately collected on a filter, well washed
with distilled water, and cautiously dried in a heat not exceeding
that of a water-bath. Washing the powder immediately is material,
because it is liable to the re-action of the nitric acid; and, while
any of the acid adheres to it, it is very subject to the action of
light. From 100 grains of mercury, about 130 of the powder are
obtained.
This powder, when struck on an anvil with a hammer, explodes with a
sharp stunning noise, and with such force as to indent both hammer and
anvil. Three or four grains are sufficient for one experiment.
