Extended information
Glass is an amorphous inorganic non-metallic material. It is generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added of. Its main components are silicon dioxide and other oxides.

The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to separate wind and transmit light. It is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called plexiglass.
