Webster's Revised Unabridged Dictionary
    • n Borax A white or gray crystalline salt, with a slight alkaline taste, used as a flux, in soldering metals, making enamels, fixing colors on porcelain, and as a soap. It occurs native in certain mineral springs, and is made from the boric acid of hot springs in Tuscany. It was originally obtained from a lake in Thibet, and was sent to Europe under the name of tincal. Borax is a pyroborate or tetraborate of sodium, Na2B4O7.10H2O.

Century Dictionary and Cyclopedia
    • n borax Sodium tetraborate or pyroborate, Na2B4O7 + 10H2O, a salt formed by the union of boracic acid and soda. It is a white crystalline solid, slightly soluble in cold water, having a sweetish alkaline taste. It occurs in nature in solution in the water of lakes in Tibet, Tatary, China, and California, and is obtained from these waters by evaporation and crystallization. The United States is now almost wholly supplied with borax from California. Borax is also prepared artificially from soda and boracic acid. It is much used as a flux in assaying operations, and for cleaning the surfaces of difficultly fusible metals previous to soldering, since when melted it dissolves the metallic oxids which form on their surfaces when heated. It is also used in glass and enamel manufacture; as an antiseptic, particularly in foods, because its action on the system is feeble even in comparatively large doses; and as a detergent. Crude borax is also called tincal.
