Tin was first smelted in combination with copper around 3500 BC to produce bronze.

The oldest artifacts date from around 2000 BC.

Cassiterite, the tin oxide form of tin, was most likely the original source of tin in ancient times.

British scientist Robert Boyle published a description of his experiments on the oxidation of tin in 1673. The Latin word for tin is stannum 64 1880 Jean de Marignac Switzerland Named after J. "Gadolin", a Finnish chemist and minerologist

Tin is considered to be non-toxic but most tin salts are toxic
When a bar of tin is bent, a crackling sound known as the tin cry can be heard
Tin is used as a coating on the surface of other metals to prevent corrosion.

It has long been used as a solder in the form of an alloy with lead.

Tin salts sprayed onto glass are used to produce electrically conductive coatings.

Tin chloride is used as a mordant in dyeing textiles and for increasing the weight of silk.
