Referred to in Genesis as brimstone, meaning "a stone that burns," elemental sulfur, which does readily burn in air, has been known since ancient times. The word derives from sulvere and sulphur (Sanskrit and Latin, respectively). Major sulfur deposits are found in the salt domes ubiquitous to the Gulf Coast of the U.S.; sulfur is the 16th most abundant element in nature. Recovery is by melting with superheated water, a commercial process developed by Herman Frasch in the 1890s and still in use today.
