Glass is formed by the melting of sand and other chemicals (soda ash, limestone, quartz).

Glass is usually divided into oxide glass and non-oxide glass according to the main components. Non-oxide glass varieties and the number is small, mainly chalcogenide glass and halide glass. Chalcogenide glass anions are mostly sulfur, selenium, tellurium, etc., can cut off short-wavelength light through yellow, red, and near and far infrared light, the resistance is low, with switching and memory characteristics. Halide glass has low refractive index, low dispersion and is used as optical glass.

Ordinary glass chemical composition is Na2O · CaO · 6SiO2, the main component is silica, is a random structure of amorphous solids. Widely used in buildings, used to wind and light, is a mixture. Another mixed with some metal oxides or salts to show the color of colored glass, and by special methods such as made of tempered glass. Sometimes transparent plastic (such as polymethyl methacrylate) is also called plexiglass.
