Century Dictionary and Cyclopedia
    • n talc A magnesian silicate, usually consisting of broad, flat, smooth laminæ or plates, unctuous to the touch, of a shining luster, translucent, and often transparent when in very thin plates. Its prevailing colors are white, apple-green, and yellow. There are three principal varieties of talc—foliated, massive (including soap-stone or steatite), and indurated. Indurated talc is used for tracing lines on wood, cloth, etc., instead of chalk. Talc is not infrequently formed by the alteration of other minerals, particularly the magnesian silicates of the pyroxene group; thus, rensselaerite is talc pseudomorphous after pyroxene, and a fibrous form of talc (sometimes called agalite), pseudomorph after enstatite, is found at Edwards, New York, and when finely ground is used in giving a gloss to paper. Talc is also used as a lubricator, and steatite or soapstone for hearthstones, etc.
    • talc To treat, or rub with talc: as, in photography, to talc a plate to which it is desired to prevent the adherence of a film.
