Lamb and Flag' Cornish tin.

One piece "Lamb & Flag" ingot of tin produced by the Cornish Tin Smelting Co. Redruth

Tin is extracted mainly from cassiterite, or tin oxide, which is found in Malaya, the East Indies, Bolivia and to a small extent in Cornwall. About one-half of the tin produced is used in tinplate, whilst the tin's low melting point and ready ability to alloy make it useful for soldering. Pewter and bearing metals also contain tin. A recent use for molten tin is in the float process for making glass, which involves floating molten glass on the surface of a tin bath.
