Zeolite


ZEOLITE, noun [Gr., to boil, to foam; stone.] A mineral, so named by Cronstedt from its intumescence before the blowpipe. Many substances have been confounded under this name, particularly such as are fusible by the blowpipe without addition, and exhibit a phosphoric brilliancy at the moment of fusion. Hauy makes two species of zeolite which he calls mesotype and stilbite. Werner makes four subspecies, which he calls maly zeolite fibrous zeolite radiated zeolite and foliated zeolite He makes zeolite a generic name, and Jameson, who adopts this theory, arranges in this family prehnite, zeolite apophyllite, cubicite, called by Hauy analcime, chabasite, cross-stone, laumonite, dipyre, natrolite, and wavellite. zeolite commonly occurs in a four sided prism, terminated by a four sided pyramid; often in small fibrous masses.
