History of Ceramics

---

Ceramic tiles are made of clay as the main raw material and other natural mineral raw materials through selection, crushing, mixing, calcining and other processes. Divided into daily ceramics, architectural ceramics, electric porcelain. The main raw materials used in the above ceramic products are natural silicate minerals (such as clay, feldspar, quartz), so they belong to the category of silicates and products.

my country is a big country in the production of ceramics, and the production of ceramics has a long history and brilliant achievements. The earliest firing in my country was pottery. Due to the long-term practice and accumulation of experience by the ancient people, new breakthroughs have been made in the development and use of glaze in the selection and refining of raw materials, the improvement of kilns and the increase in firing temperature, and the transformation from pottery to porcelain has been realized. New processes, new technologies and new equipment in the ceramic industry are emerging one after another.

Interior wall tiles are a type of ceramic tiles, which are mainly used for interior wall decoration. The interior wall tiles are composed of three parts, the body, the bottom glaze layer, and the surface glaze layer. The water absorption rate of the blank bottom is generally about 10%-18% (water absorption rate refers to the percentage of the water absorbed by the pores in the ceramic product as a percentage of the product).
