MEERSCHAUM
, a See also:German word designating a soft See also: The mineral is associated with See also:magnesite (magnesium carbonate), the See also:primitive source of both minerals being a See also:serpentine . When first extracted the meerschaum is soft, but it hardens on exposure to See also:solar See also:heat or when dried in a warm See also:room . Meerschaum is found also, though less abundantly, in See also:Greece, as at See also:Thebes, and in the islands of See also:Euboea and See also:Samos; it occurs also in serpentine at Hrubschitz near Kromau in See also:Moravia . It is found to a limited extent at certain localities in See also:France and See also:Spain, and is known in See also:Morocco . In the See also:United States it occurs in serpentine in See also:Pennsylvania (as at See also:Nottingham, See also:Chester See also:county) and in See also:South Carolina and See also:Utah . Meerschaum has occasionally been used as a substitute for See also:soap and See also:fuller's See also:earth, and it is said also as a See also:building material; but its See also:chief use is for See also:tobacco-pipes and See also:cigar-holders . The natural nodules - are first scraped to remove the red earthy See also:matrix, then dried, again scraped and polished with See also:wax . The rudely shaped masses thus prepared are sent from the See also:East to See also:Vienna and other manufacturing centres, where they are turned and carved, smoothed with See also:glass-See also:paper and Dutch rushes, heated in wax or stearine, and finally polished with bone-ash, &c . Imitations are made in See also:plaster of See also:Paris and other preparations . The soft, white, earthy mineral from Ungbanshyttan, in Vermland, See also:Sweden, known as See also:aphrodite (d¢,See also:pbs, foam), is closely related to meerschaum . It may be noted that meerschaum has sometimes been called magnesite (q.v.) . |
