Patterned glass is a glass manufacturing technique that creates patterns and textures by applying pressure and heat to the glass surface. The following are the general technical steps for patterned glass production:
1. Glass preparation: Select suitable glass raw materials, such as silica sand, alkali, lime, etc., mix them according to a certain proportion, and melt them into liquid glass at high temperature.
2. Embossing mold production: According to the design requirements, make a suitable embossing mold. Molds can be made of metal, ceramics and other materials.
3. Glass embossing: Pour molten glass into a preheated embossing mold, and then use a press to apply pressure to make the glass contact the mold and form patterns and textures.
4. Cooling and annealing: Place the embossed glass product in the cooling chamber to allow it to cool slowly. Then, an annealing process is performed to eliminate internal stress and increase the strength of the glass.
5. Cutting and processing: Patterned glass is cut, polished and processed as needed to meet different application needs.
6. Cleaning and packaging: Clean the patterned glass to remove dirt and impurities on the surface. It is then packaged for shipping and sale.
