Tin has been known for thousands of years. Cassiterite, or Tin Oxide, is the main source of Tin. Tin is used mainly as a coating for other metals to prevent corrosion or other chemical action. Tin cans are actually steel cans coated with Tin; this helps to preserve the food. Pewter, solder, and bronze are Tin alloys. [LM] {RW}
