Legend

Name origin:	Latin: sulphur (brimstone)
Description:	Tasteless, odorless, pale yellow, brittle solid. Tenth most abundant element in the universe.
Discovered by:	Known to the ancients
Year:	--
Place:	Unknown
Sources:	Found in pure form and in ores like cinnabar, galena, sphalerite and stibnite. Pure form is obtained from undergound deposits by the Frasch process.
Use(s):	Used in matches, gunpowder, medicines, rubber and pesticides, dyes and insecticides. Also for making sulfuric acid (H2SO4).
