Unisilicate :: Unisilicate (n.) A salt of orthosilicic acid, H4SiO4; -- so called because the ratio of the oxygen atoms united to the basic metals and silicon respectively is 1:1; for example, Mg2SiO4 or 2MgO.SiO2..

Flint Glass :: Flint glass () A soft, heavy, brilliant glass, consisting essentially of a silicate of lead and potassium. It is used for tableware, and for optical instruments, as prisms, its density giving a high degree of dispersive power; -- so called, because formerly the silica was obtained from pulverized flints. Called also crystal glass. Cf. Glass..

Stilt :: Stilpnomelane (n.) A black or greenish black mineral occurring in foliated flates, also in velvety bronze-colored incrustations. It is a hydrous silicate of iron and alumina..

Amphibole :: Amphibole (n.) A common mineral embracing many varieties varying in color and in composition. It occurs in monoclinic crystals; also massive, generally with fibrous or columnar structure. The color varies from white to gray, green, brown, and black. It is a silicate of magnesium and calcium, with usually aluminium and iron. Some common varieties are tremolite, actinolite, asbestus, edenite, hornblende (the last name being also used as a general term for the whole species). Amphibole is a constit

Bisilicate :: Bisilicate (n.) A salt of metasilicic acid; -- so called because the ratio of the oxygen of the silica to the oxygen of the base is as two to one. The bisilicates include many of the most common and important minerals.

Heulandite :: Heulandite (n.) A mineral of the Zeolite family, often occurring in amygdaloid, in foliated masses, and also in monoclinic crystals with pearly luster on the cleavage face. It is a hydrous silicate of alumina and lime..

Gadolinite :: Gadolinite (n.) A mineral of a nearly black color and vitreous luster, and consisting principally of the silicates of yttrium, cerium, and iron..

Willemite :: Willemite (n.) A silicate of zinc, usually occurring massive and of a greenish yellow color, also in reddish crystals (troostite) containing manganese..

Silicate :: Silicate (n.) A salt of silicic acid.

Hauynite :: Hauynite (n.) A blue isometric mineral, characteristic of some volcani/ rocks. It is a silicate of alumina, lime, and soda, with sulphate of lime..

Borosilicate :: Borosilicate (n.) A double salt of boric and silicic acids, as in the natural minerals tourmaline, datolite, etc..

Protosilicate :: Protosilicate (n.) A silicate formed with the lowest proportion of silicic acid, or having but one atom of silicon in the molecule..

Phillipsite :: Phillipsite (n.) A hydrous silicate of aluminia, lime, and soda, a zeolitic mineral commonly occurring in complex twin crystals, often cruciform in shape; -- called also christianite..

Crocidolite :: Crocidolite (n.) A mineral occuring in silky fibers of a lavender blue color. It is related to hornblende and is essentially a silicate of iron and soda; -- called also blue asbestus. A silicified form, in which the fibers penetrating quartz are changed to oxide of iron, is the yellow brown tiger-eye of the jewelers..

Zeolite :: Zeolite (n.) A term now used to designate any one of a family of minerals, hydrous silicates of alumina, with lime, soda, potash, or rarely baryta. Here are included natrolite, stilbite, analcime, chabazite, thomsonite, heulandite, and others. These species occur of secondary origin in the cavities of amygdaloid, basalt, and lava, also, less frequently, in granite and gneiss. So called because many of these species intumesce before the blowpipe..

Pyroxene :: Pyroxene (n.) A common mineral occurring in monoclinic crystals, with a prismatic angle of nearly 90¡, and also in massive forms which are often laminated. It varies in color from white to dark green and black, and includes many varieties differing in color and composition, as diopside, malacolite, salite, coccolite, augite, etc. They are all silicates of lime and magnesia with sometimes alumina and iron. Pyroxene is an essential constituent of many rocks, especially basic igneous rocks, as basa

Stile :: Stilbite (n.) A common mineral of the zeolite family, a hydrous silicate of alumina and lime, usually occurring in sheaflike aggregations of crystals, also in radiated masses. It is of a white or yellowish color, with pearly luster on the cleavage surface. Called also desmine..

Greensand :: Greensand (n.) A variety of sandstone, usually imperfectly consolidated, consisting largely of glauconite, a silicate of iron and potash of a green color, mixed with sand and a trace of phosphate of lime..

Allanite :: Allanite (n.) A silicate containing a large amount of cerium. It is usually black in color, opaque, and is related to epidote in form and composition..

Fluosilicate :: Fluosilicate (n.) A double fluoride of silicon and some other (usually basic) element or radical, regarded as a salt of fluosilicic acid; -- called also silicofluoride..
