| titleOfInvention | Method of treating glass surface |
| abstract | This invention relates to a chemical glass processing technology. The aim of the invention is to ensure the identity of the heat history of the gradient in mass production. To do this, in the method of glass surface treatment by ion exchange matting in molten lithium salt, repeated ion exchange treatment in a dye metal salt solution and heat treatment, the glass is heat treated in molten salts of potassium nitrate, rubidium or cesium nitrate or potassium nitrate at a temperature below the starting softening point. glass As a result of the three-stage treatment of the gradans, their surface becomes matted and blackened, and also the hardening of the matted surface occurs. 1 tab. |
