In modern society, people need to use a large amount of glass products in their daily lives,glass has stable properties, is resistant to strong acids and alkalis, and is hard and durable, making it one of the raw materials required for most important equipment. Today we will further understand the coloring and processing methods of colored glass.
Colored glass is made by adding coloring agents to ordinary glass, and the amount of coloring, melting time, and melting temperature can all affect the depth of the fired color to varying degrees. Using colloidal colorants such as gold, silver, copper, selenium, sulfur, etc. to suspend smaller particles inside the glass and color the glass. During the firing process, any type of colorant is added with a flux.
Metal films such as gold, silver, copper, or metal oxide films such as In2O3, SnO2, TiO2 can be produced by methods such as vacuum evaporation, vacuum cathode sputtering, and reactive sputtering. Due to the different thickness and refractive index of the film layer, interference and reflection films of different colors can be formed.
In the float glass production line, surface colored glass can be produced using either electric float method or thermal spraying method. Glazed glass can also be made by printing or spraying glass colored glaze, etc.
