Zgodovina
By the 3rd century, the Chinese discovered that sulfur could be extracted from pyrite.
Indian alchemists wrote extensively about the use of sulfur in alchemical operations with mercury, from the eighth century AD onwards.
In 1777, Antoine Lavoisier helped convince the scientific community that sulfur was an element, not a compound.

Uporabe
Sulfur's main commercial use is as a reactant in the production of sulfuric acid.
Sulfur is a component of black gunpowder, and is used in the vulcanization of natural rubber and a fungicide.
It is used to make sulfite paper and other papers, to fumigate, and to bleach dried fruits.
It is also used extensively in making phosphatic fertilizers.
