(1) Ordinary glass (Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2).

(2) Quartz glass (glass made of pure quartz with SiO2 as the main raw material).

(3) Tempered glass (the same composition as ordinary glass).

(4) Potassium glass (K2O, CaO, SiO2).

(5) Borate glass (SiO2, B2O3).

Tinted glass is made by adding some metal oxides to it.Cu2O - red;CuO -- turquoise;Cdos -- light yellow;Co2O3 - blue;Ni2O3 -- dark green;MnO2 -- blue-purple;Colloidal Au -- red;Colloidal Ag -- yellow).

(7) Color-changing glass (high-grade colored glass that USES the oxides of rare earth elements as colorants).

(8) Optical glass (a small amount of light-sensitive substances, such as AgCl and AgBr, and a very small amount of sensitizers, such as CuO, are added to ordinary borosilicate glass raw materials to make the glass more sensitive to light).

(9) Rainbow glass (made from ordinary glass materials by adding a large amount of fluoride, a small amount of sensitizer and bromide).

(10) Protective glass (in the manufacturing process of ordinary glass, add appropriate auxiliary materials, so that it has the function of protecting personal safety by preventing strong light, strong heat or radiation from penetrating.Such as gray - dichromate, iron oxide absorption of ultraviolet and some visible light;Blue-green -- nickel oxide and ferrous oxide absorb infrared and some visible light;Lead glass -- lead oxide absorbs X-rays and R rays;Dark blue - Dichromate, ferrous oxide, iron oxide absorb ultraviolet, infrared and most visible light;Add cadmium oxide and boron oxide to absorb neutron flow.

(11) Crystal glass (also called crystal glass or glass ceramics, is made by adding gold, silver, copper and other crystal nuclei in ordinary glass, instead of stainless steel and precious stones, as radar cover and missile head).

(12) Glass fiber (a fiber of several microns to several thousand microns in diameter drawn or blown from molten glass, having the same composition as glass).

(13) Glass filament (i.e. long glass fiber).

(14) Glass fiber reinforced plastics (reinforced plastics with similar strength to steel made by combining epoxy resin with glass fiber).

Cellophane (transparent cellulose film made from a solution of viscose).

(16) An aqueous solution of sodium silicate (Na2SiO3), named because it has some of the same components as ordinary glass.

(17) Metallic glass (a glassy metal usually made by rapidly cooling molten metal).

Fluorite (fluorspar) (CaF2, colorless and transparent, used as a prism and a diopter in optical instruments).
