A More Powerful Fulminating Powder
The most wonderful instance of chemical detonation is formed by the
combination of volatile alkali with silver. Gunpowder, or fulminating
gold, are not to be compared with this invention, and the great danger
attending its manufacture prevents us from giving a methodical account
of its preparation to our readers, particularly as it can be
purchased, properly prepared, of the chemists.
The slightest agitat
on or friction is sufficient to cause its
explosion. When it is once obtained, it can no longer be touched with
safety. The falling of a few atoms of it, from a small height,
produces an explosion; a drop of water falling on it has the same
effect. No attempt, therefore, can be made to enclose it in a bottle,
but it must be let alone in the capsule, wherein, by evaporation, it
obtains this terrible property. To make this experiment with safety,
no greater quantity than a grain of silver should be used; the last
process of drying should be made in a metallic vessel, and the face of
the operator defended by a mask with strong glass eyes.
