Known since ancient times, sulfur is one of
the few non-metals that can be found pure
in nature. This yellow, crystalline element is
found in large amounts near volcanic craters.
Another name for sulfur is “brimstone”, which
refers to the way its crystals burn, melting intoa blood-red liquid. In some religions, brimstone
is thought to be the fuel that burns in the
underworld. Pure sulfur is extracted from
underground deposits using hot water. The hot
liquid sulfur is then pumped to the surface.
