SULPHUR.

Sulphur, also called Brimstone, is a natural production, and is

found either pure, or combined with metals forming ores, for the

most part called “pyrites,” as, iron pyrites, copper pyrites, &c.

In chemical language these compounds are called “sulphurets” or

“sulphides.” Sulphur is one of the elements; that is to say, it is

a simple body, or one neither capable of being made nor separated

into other ingredients. It is crystalline, of a bright yellow color,

very inflammable and volatile, burns with a blue flame and gives off

pungent fumes of sulphurous acid. It is got pure by distillation from

various substances containing it, and in Sicily is found nearly pure

as a volcanic product. Sulphur is chiefly used for the manufacture of

sulphuric acid and gunpowder, and was also largely used for making

matches, but phosphorus (a still more inflammable substance) has

almost superseded it in the manufacture of this necessary article.
