Tin Element, Alloys and Symbols

• Stannite, Cu2S.FeS.SnS.
• Cassiterite, SnO2.

The only ore of tin of important is the oxide, cassiterite. This is a mineral which, while occurring in small quantities in many localities, is found only in a comparatively few commercial deposits. The United States at present produces only a small amount of tin ore.

Tin is chiefly used in the coating or “tinning” of metals, especially iron. The tin plate thus formed is used in roofing, in various utensils, etc. An amalgam of tin and mercury is used

in “silvering” mirrors. Various Alloys are valuable, such as solder(tin and lead), bronze and bell metal (copper and tin). The artificial oxide of tin is used as a polishing powder. Stannie chloride is employed as a mordant in dyeing.
