Discovery: 1450 Basil Valentine (DE)

Bismuth was discovered by Basil Valentine (DE) in 1450. The origin of the name comes from the German words 'Weisse Masse' meaning 'white mass'; now spelled 'wismut' and 'bisemutum'. It is a hard, brittle, steel-grey metal with a pink tint. It is stable in oxygen and water but dissolves in concentrated nitric acid. Bismuth can be found free in nature and in minerals like bismuthine (Bi2S3) and in bismuth ochre (Bi2O3) Main use is in pharmaceuticals and low melting point alloys used as fuses.
