What is glass made of?

Glass is formed by melting together sand and other chemicals (the main raw materials are: soda ash, limestone, quartz).
Glass is a kind of amorphous inorganic nonmetallic material, generally with a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as raw materials after high temperature melting in the cooling process is quickly solidified. The main chemical composition of glass is the silicate series, which includes sodium glass, potassium glass, calcium glass, aluminum glass and other categories.
