[AS.] A metal white, like silver, easily melted or beaten out. Owing to the fact that it does not tarnish either in dry or moist air, it is much used for cooking-vessels, especially in the form of tin-plate. Tin is also used in the preparation of several important alloys, such as bronze, pewter, Britannia metal, bell-metal, etc. It does not occur in the native state, the tin of commerce being obtained from the dioxide, known to miners as tinstone. The chief European supply of this mineral is derived from the mines of Cornwall. It is also met with in the Malayan peninsula, the isle of Banca, and Australia. Deposits have been found in the United States, but none that paid to work. In order to prepare the metal, the tinstone is broken into fragments ; and as it remains among the debris unchanged in character, it can, like gold, be separated from the lighter portions of rock by washing. It is then reduced to the metallic state by roasting in a furnace. - Tin-foil, tin beaten out very thin, like a leaf.
