Glassiness :: Glassiness (n.) The quality of being glassy.

Glass-rope :: Glass-rope (n.) A remarkable vitreous sponge, of the genus Hyalonema, first brought from Japan. It has a long stem, consisting of a bundle of long and large, glassy, siliceous fibers, twisted together..

Pitchstone :: Pitchstone (n.) An igneous rock of semiglassy nature, having a luster like pitch..

Phenacite :: Phenacite (n.) A glassy colorless mineral occurring in rhombohedral crystals, sometimes used as a gem. It is a silicate of glucina, and receives its name from its deceptive similarity to quartz..

Crystallite :: Crystallite (n.) A minute mineral form like those common in glassy volcanic rocks and some slags, not having a definite crystalline outline and not referable to any mineral species, but marking the first step in the crystallization process. According to their form crystallites are called trichites, belonites, globulites, etc..

Hyalospongia :: Hyalospongia (n. pl.) An order of vitreous sponges, having glassy six-rayed, siliceous spicules; -- called also Hexactinellinae..

Leucite :: Leucite (n.) A mineral having a glassy fracture, occurring in translucent trapezohedral crystals. It is a silicate of alumina and potash. It is found in the volcanic rocks of Italy, especially at Vesuvius..

Pearlstone :: Pearlstone (n.) A glassy volcanic rock of a grayish color and pearly luster, often having a spherulitic concretionary structure due to the curved cracks produced by contraction in cooling. See Illust. under Perlitic..

Anorthite :: Anorthite (n.) A mineral of the feldspar family, commonly occurring in small glassy crystals, also a constituent of some igneous rocks. It is a lime feldspar. See Feldspar..

Sanidine :: Sanidine (n.) A variety of orthoclase feldspar common in certain eruptive rocks, as trachyte; -- called also glassy feldspar..

Nephelite :: Nephelite (n.) A mineral occuring at Vesuvius, in glassy agonal crystals; also elsewhere, in grayish or greenish masses having a greasy luster, as the variety elaeolite. It is a silicate of aluminia, soda, and potash..

Glassen :: Glassen (a.) Glassy; glazed.

Devitrification :: Devitrification (n.) The act or process of devitrifying, or the state of being devitrified. Specifically, the conversion of molten glassy matter into a stony mass by slow cooling, the result being the formation of crystallites, microbites, etc., in the glassy base, which are then called devitrification products..

Glassy :: Glassy (a.) Made of glass; vitreous; as, a glassy substance..

Cabazite :: Cabazite (n.) A mineral occuring in glassy rhombohedral crystals, varying, in color from white to yellow or red. It is essentially a hydrous silicate of alumina and lime. Called also chabasie..

Glass-sponge :: Glass-sponge (n.) A siliceous sponge, of the genus Hyalonema, and allied genera; -- so called from their glassy fibers or spicules; -- called also vitreous sponge. See Glass-rope, and Euplectella..
