Tin has been mined and used to make objects both decorative and utilitarian for over 3,000 years. Tin is the fourth most precious metal in common usage after platinum, gold and silver . It is bright, attractive and extremely versatile. Pewter is an alloy that is made almost entirely from pure tin. Modern pewter contains about 92% tin and added to this are small amounts of antimony, copper or bismuth to give additional strength. Tin is a plentiful natural resource and tin mining has little or no impact on the environment.
