ETYM Old Eng. glas, gles, AS. glaes; akin to Dutch, German, Dan., and Swed. glas, Icel. glas, gler, Dan. glar; cf. AS. glaer amber, Latin glaesum. Related to Glare, Glaze.
Transparent or translucent substance that is physically neither a solid nor a liquid. Although glass is easily shattered, it is one of the strongest substances known. It is made by fusing certain types of sand (silica); this fusion occurs naturally in volcanic glass (see obsidian).
In the industrial production of common types of glass, the type of sand used, the particular chemicals added to it (for example, lead, potassium, barium), and refinements of technique determine the type of glass produced. Types of glass include: soda glass; flint glass, used in cut-crystal ware; optical glass; stained glass; heat-resistant glass; and glasses that exclude certain ranges of the light spectrum. Blown glass is either blown individually from molten glass (using a tube up to 1.5 m/4.5 ft long), as in the making of expensive crafted glass, or blown automatically into a mold—for example, in the manufacture of light bulbs and bottles; pressed glass is simply pressed into molds, for jam jars, cheap vases, and light fittings; while sheet glass, for windows, is made by putting the molten glass through rollers to form a “ribbon”, or by floating molten glass on molten tin in the “float glass” process; fiberglass is made from fine glass fibers. Metallic glass is produced by treating alloys so that they take.
