Ceramics are the collective name of pottery and porcelain, and it is also a kind of arts and crafts in our country. As far away as the Neolithic Age, our country has rough and simple colored pottery and black pottery. Pottery and porcelain have different textures and properties. Pottery is made of clay with high viscosity and strong plasticity as the main raw material. It is opaque, has fine pores and weak water absorption, and the sound is turbid. Porcelain is made of clay, feldspar and quartz. It is translucent, non-absorbent, corrosion-resistant, hard and tight, and brittle. China's traditional ceramic arts and crafts are of high quality and beautiful shape, with high artistic value, and are famous in the world.

Ceramic materials refer to a class of inorganic non-metallic materials made of natural or synthetic compounds through forming and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural material and tool material. Because ceramics also have some special properties, they can also be used as functional materials.

Ceramics can be divided into seven types: polished tiles/vitrified tiles, glazed tiles, general tiles, microlite, antique tiles, cement tiles, and mosaics. The technology of the ceramic industry is developing with each passing day, and the selection of materials is not limited to traditional raw materials such as clay, feldspar, and quartz. Some new materials are also used as raw materials for production, such as non-silicate and non-oxide range. Therefore, our understanding of ceramics should not be limited to traditional materials and processes, but should keep up with the changes brought about by technological development. At present, ceramic products used in domestic buildings are divided into interior wall tiles, exterior wall tiles and floor tiles according to their uses. According to the material classification: porcelain brick, semi-porcelain brick and ceramic tile, according to the molding method is divided into dry pressing method, plastic method and grouting method.

Due to the many processing links of ceramic materials, the price also varies from tens to thousands due to the quality of the selected materials.

Ceramics can be used for floor laying, which is very concise.

Ceramics can be used to make handicrafts, especially Chinese porcelain. It is the best porcelain in the world and has a glorious history.
