1.Oridinary glass（Na2SiO3、CaSiO3、SiOor Na2O·CaO·6SiO2）
2. Quartz glass（glass）The glass made with pure quartz as the main raw material only contain SiO2.
3. Tempered glass(Na2SiO3、CaSiO3、SiOor Na2O·CaO·6SiO2)
4. Tinted glass(Some metal oxides are added to the ordinary glass manufacturing process.CU2o-red; CUO-turquoise;Cdos-pale,yellow;CO2O3-blue;Ni2O3-dark green;MnO2,purple;Colloidal Au-red;colloi -dal Ag-yellow)
5. Protective glass(suitable auxiliary materials are added in the ordinary glass manufacturing process to make it have the function of protecting personal safety by preventing strong light,strong heat or radiation transmission.Such as gray-dichromate,iron oxide absorption of ultraviolet light and part of the visible light;blue-green-nickel oxide and ferrous oxide absorb infrared and part of visible light;lead glass-lead oxide absorbs-rays and rays;dark blue-bichromate ferrous oxide,iron oxide absorb ultraviol -et,infrared and most visible light;add cadmium oxide and born oxide to absorb the neutron stream.
6. Glass ceramics:Also known as crystal glass or ceramics,is in ordinary glass by adding gold,silver,cop -per and other crystal made,instead of stainless steel and gems,as a radar-shield and missile head.
