A ceramic mug is a cup made of ceramics and used for drinking wine, water, tea, etc. The so-called “ceramic” is a form of clay made of clay or other inorganic non-metallic materials, processed by molding, sintering and other processes to decorate and protect the walls and floors of buildings. After drying, it is heated to a certain degree to harden it and no longer dissolve in water.
The main ingredients of ceramic mugs：
Including kaolin, clay, porcelain stone, porcelain clay, colorant, blue and white material, lime glaze, lime alkali glaze, etc.
Specific production steps：
- Sculpture products based on artwork
- Use plaster to make bulk mold after splitting (make sample mold)
- Mold drying
- Clay mud, make adobe, (through high pressure, rolling or grouting) shaping
- Blank trimming (connection, punching; trimming; scraping line; blank washing)
- Apply glaze after drying the green body
- Glaze firing
- Into ceramic cup products
- Painted or decals
- Baked flowers make perfect products
Precautions：
Sculpture the product prototype according to the artwork: due to the different shrinkage rate of each kind of soil due to the firing temperature, the sculptured product prototype is larger than the final product.
- The shrinkage rate of high temperature products is; 1.16-1.17 (the firing temperature is about 1350)
- The shrinkage rate of the medium temperature product is: 1.15 (the firing temperature is about 1250)
- The shrinkage rate of dolomite is about 1.05 (the firing temperature is about 1050)
