Historie
Bismuth has been known since ancient times, so no one person is credited with its discovery.
The element was confused in early times with tin and lead because of its resemblance to those elements.
In 1753, French chemist Claude François Geoffroy demonstrated that this metal is distinct from lead and tin.

Bruksområder
Bismuth is used in producing malleable irons and is used as a catalyst for making acrylic fibers.
Bismuth oxychloride is used in cosmetics, as a pigment in paint for eye shadows, hair sprays and nail polishes.
It has also been used as a replacement for lead in shot, bullets and less-lethal riot gun ammunition.
