For hundreds of years, people have always thought that glass is green and cannot be changed. Later, it was found that the green color came from a small amount of the raw materials, and the tetravalent manganese was reduced to trivalent manganese and was purple. Optically, yellow and purple can complement each other to a certain extent, and when mixed together to become white light, the glass will not cast color.
The glass we are using is made of quartz sand, soda ash, feldspar and limestone at high temperature. A non-crystalline solid material that gradually increases in viscosity during cooling of the melt. Brittle and transparent. There are quartz glass, silicate glass, soda lime glass, fluoride glass and so on. Usually refers to silicate glass, which is obtained by using quartz sand, soda ash, feldspar and limestone as raw materials, after mixing, high temperature melting, homogenization, processing and forming, and then annealing. It is widely used in construction, daily use, medical treatment, chemistry, electronics, instrumentation, nuclear engineering and other fields.
Glass is an ancient building material. With the rapid improvement of modern technology and the rapid development of application technology, various types of glass with unique functions have come out, prospering the glass family.
