1, adding a small amount of glass colorant when melting the glass can produce a variety of colored glass. Copper oxide or chromium oxide produces green; Cobalt oxide produces blue; Manganese dioxide produces purple; Tin dioxide or calcium fluoride produces milky white; Uranium compounds produce yellow-green fluorescence

Colloidal selenium produces red jade; colloidal gold produces red, reddish purple, or blue; cuprous oxide produces red, green, or blue; ferrous compounds produce green, and when the amount is large, it is black; iron compounds produce yellow.

2, when making glass, because the raw material contains the impurity of ferrous iron, often make the glass green, can add a small amount of manganese dioxide or selenium, make it become the colorless glass.

3, Glass is formed by the melting of sand and other chemicals (mainly raw materials are: soda, limestone, quartz). A continuous network structure is formed at the time of melting, the viscosity gradually increases during the cooling and hardens to render the silicate-based non-metal material that crystallizes. The chemical composition of ordinary glass is Na2O·CaO·6SiO2. The main component is silica, which is an amorphous structure with irregular structure.
