Process materials and classification of ceramic cups

 

Ceramics are all kinds of products made from natural clay and various natural minerals by crushing, mixing, shaping and calcining. People used to call ceramics, which are made of pottery and fired at high temperature in a special kiln. Ceramics are the general name of ceramics and ceramics. The traditional concept of ceramics refers to all artificial industrial products, such as clay and other inorganic nonmetallic minerals. It includes all kinds of products made by mixing, forming and calcining clay or mixtures containing clay. From the coarser earth implements to the finest fine pottery and porcelain belong to its range. Its main raw materials are silicate minerals (such as clay, quartz, etc.) from nature. Therefore, it belongs to the category of "silicate industry" together with glass, cement, enamel, refractory and other industries. The main producing areas of ceramics are Jingdezhen, Liling, Gao'an, Fengcheng, Pingxiang, Lichuan, Foshan, Chaozhou, Dehua, Zibo, Tangshan and Beiliu. Besides, Jingdezhen is China's capital of porcelain.

Common ceramic materials include clay, alumina, kaolin and so on. Ceramic materials are generally of high hardness but poor plasticity. In addition to being used in food utensils and decorations, ceramics also play an important role in the development of science and technology. Ceramic raw material is the earth's original large amount of resources, clay has been quenched. The clay is tough, plastic at room temperature, sculptible at micro-drying, grindable at all drying; pottery can be filled with water when fired to 700 degrees; pottery can be ceramized when fired to 1230 degrees, which can hardly absorb water and resist high temperature and corrosion. The flexibility of its usage has various creative applications in today's culture and technology. Invented pottery. Ceramic materials are mostly oxides, nitrides, borides and carbides.

Ceramic Material: Compared with ceramics, ceramics are relatively loose in texture and coarse in particle size. The firing temperature is generally between 900 ~1500 ~C. The temperature is lower. After firing, the color becomes interesting naturally. It is simple and generous, and it has become one of the most popular plastic performance materials for many artists. There are many kinds of pottery, such as black pottery, white pottery, red pottery, grey pottery and yellow pottery. Red pottery, grey pottery and black pottery are made of pottery clay with high iron content. Iron pottery clay is red in oxidizing atmosphere and grey or black in reducing atmosphere.

Porcelain Material: Compared with pottery, the quality of porcelain is hard, fine, strictly forbidden, high temperature resistance, rich glaze color and so on. The firing temperature is generally around 1300 C. It is often described as "sound like a gorgeous mirror, bright like jade, thin like paper". Porcelain gives people a feeling of nobility and gorgeousness, contrary to the plainness of pottery. Therefore, when many artists create ceramic works of art, they will emphasize the different sensory enjoyment brought by the texture of pottery or porcelain. Therefore, it is necessary to analyze and compare the characteristics of two different materials before creating.
