Historie
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.
