GEOLOGY

Detailed explanation-1: -The natural silica sand is the most preferred material in a glass industry, but in some cases where the glass plants are located far away from silica deposits, crushed quartz is also used.

Detailed explanation-2: -There are many differences between glass and quartz. The first one lies in the silicone dioxide content; glass has roughly eighty percent, while quartz can contain over ninety percent. As an amorphous substance, glass has a random molecular structure, while quartz has a symmetrical molecular structure.

Detailed explanation-3: -Rock crystal quartz is found widely distributed, some of the more notable localities being: the Alps; Minas Gerais, Brazil; Madagascar; and Japan. The best quartz crystals from the United States are found at HotSprings, Arkansas, and Little Falls and Ellenville, New York.

Detailed explanation-4: -“Quartz glass is valued for its superior optical properties (i.e. light transmittance), low coefficient of thermal expansion, and good chemical resistance. “The starting material for quartz glass production is natural quartz, cultured quartz or a synthetic precursor such as silicon tetrachloride.
