What materials do you need to make glass?
There is also colored glass mixed with certain metal oxides or salts, and tempered glass made by physical or chemical methods. Sometimes some transparent plastic (such as polymethyl methacrylate) is also called organic glass.
The chemical composition of ordinary glass is Na2O, CaO, 6SiO2, the main component is silica, is a kind of amorphous structure with irregular structure. Widely used in buildings for wind and light transmission; of mixtures.
Glass is formed by the fusion of silica and other chemicals (the main ingredients are: soda ash, limestone, quartz). A continuous network structure is formed during melting, and the silicate like non-metallic material is gradually increased and hardened in the process of cooling.
