What kind of mineral is glass made of?
Optical glass (added a small amount of light sensitive material to ordinary borosilicate glass material, such as AgCl, AgBr, etc., adding a very small amount of sensitizer, such as CuO, to make glass more sensitive to light)
Protective glass (in the ordinary glass manufacturing process to add appropriate auxiliary material, so that it has to prevent light, heat or radiation through the protection of personal safety function. Such as grey - dichromate, iron absorption in the ultraviolet and visible light; blue - Green nickel oxide, FeO absorb infrared and visible light; lead glass - lead absorption of X rays and R rays; dark blue - dichromate, ferrous oxide, iron oxide, UV absorption infrared and most visible light; adding cadmium oxide and boron oxide absorption neutron flux.
Rainbow glass (made from common glass material with a large amount of fluoride, a small amount of sensitizer and bromide)
Photochromic glass (an advanced colored glass with an oxide of rare earths as a coloring agent)
Colored glass is made by adding some metal oxides in the manufacture of ordinary glass. Cu2O - red; CuO - blue-green; CdO - pale yellow; CO2O3 - blue; Ni2O3 - dark green; MnO2 - purple; colloidal Au - red; colloidal Ag - yellow)
