Tin n.
1. Chem. An elementary substance found as an oxide in the mineral cassiterite, and reduced as a soft silvery-white crystalline metal, with a tinge of yellowish-blue, and a high luster. It is malleable at ordinary temperatures, but brittle when heated. It is softer than gold and can be beaten out into very thin strips called tinfoil. It is ductile at 2120, when it can be drawn out into wire which is not very tenacious; it melts at 4420, and at a higher temperature burns with a brilliant white light. Air and moisture act on tin very slightly. The peculiar properties of tin, especially its malleability, its brilliancy and the slowness with which it rusts make it very serviceable. With other metals it forms valuable alloys, as bronze, gun metal, bell metal, pewter and solder. It is not easily oxidized in the air, and is used chiefly to coat iron to protect it from rusting, in the form of tin foil with mercury to form the reflective surface of mirrors, and in solder, bronze, speculum metal, and other alloys. Its compounds are designated as stannous, or stannic. Symbol Sn (Stannum). Atomic weight 117.4.
