Orthoclase: The mineral Orthoclase information and pictures

Orthoclase is industrially important in the manufacture of glass and ceramics. Orthoclase crystals and twins provide information on the formation of minerals and environmental factors. Well shaped crystals and twins are highly sought after by mineral collectors, and the Moonstone variety is used as a gemstone. For additional information, see the gemstone section on Orthoclase and Moonstone.
