From The Collaborative International Dictionary of English v.0.48 :

  Tin \Tin\, n. [As. tin; akin to D. tin, G. zinn, OHG. zin, Icel.
     & Dan. tin, Sw. tenn; of unknown origin.]
     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.
        [1913 Webster]
     2. Thin plates of iron covered with tin; tin plate.
        [1913 Webster]
     3. Money. [Cant] --Beaconsfield.
        [1913 Webster]
     Block tin (Metal.), commercial tin, cast into blocks, and
        partially refined, but containing small quantities of
        various impurities, as copper, lead, iron, arsenic, etc.;
        solid tin as distinguished from tin plate; -- called also
        bar tin.

        under Fuming.
     Grain tin. (Metal.) See under Grain.
     Salt of tin (Dyeing), stannous chloride, especially so
        called when used as a mordant.
     Stream tin. See under Stream.
     Tin cry (Chem.), the peculiar creaking noise made when a
        bar of tin is bent. It is produced by the grating of the
        crystal granules on each other.
     Tin foil, tin reduced to a thin leaf.
     Tin frame (Mining), a kind of buddle used in washing tin
     Tin liquor, Tin mordant (Dyeing), stannous chloride, used
