I believe everyone has seen colored glass, so what is the principle of this kind of glass? Here's a good introduction for you.
This is the addition of colorants in ordinary glass, such as MnO 2 for purple; CoO, CoO 3 for purple red; FeO, K2Cr2O7 for green; CdS, FeO 3, SB2S3 for yellow; AuCl3, CuO for red; CuO, MnO 2, CoO, Fe3O4 for black; CaF2, SnO 2 for milky white. The amount of dyeing dose, melting time and melting temperature will affect the depth of firing color in varying degrees.
Colloidal colorants, such as gold, silver, copper, selenium and sulfur, are used to suspend very small particles in the glass and make the glass colored. In the process of firing, no matter which colorant is added, flux is added.
Colored glass of different colors is made by adding different materials. Today, we introduce the principle of making this kind of glass, hoping to help you.
