Exploding Salt
If a small quantity of powdered charcoal and hyper-oxymuriate of
potash be rubbed together in a mortar, an explosion will be produced,
and the charcoal inflamed. Three parts of this salt, and one of
sulphur, rubbed together in a mortar, produce a violent detonation. If
struck with a hammer on an anvil, there is an explosion like the
report of a pistol.
When concentrated sulphuric acid is poured upon this salt, there is a
considerable explosion; it is thrown about to a great distance,
sometimes with a red flame; and there is exhaled a brown vapour,
accompanied with a strong odour.
