  Today Malaysia and Indonesia are the main producers of raw tin where open surface mining is used. Bolivia also produces tin, although underground mining is used.

Tin ore is refined in the producing countries. It is poured into bars and arrives at our workshop with virtually 100% purity. A basic element symbolized by Sn, tin is a light-colored, relatively light metal. Its exact weight is 7.3, and its melting point lies at 232° centigrade.

Alone, pure tin is too soft and brittle for manufacturing purposes. It must be alloyed with copper and antimony. These additives make up about 5% of pewter and give the material more strength and better casting qualities.
