What is ceramics? Explain its main performance characteristics from the perspective of organizational structure.

1. A vessel made of clay is called pottery, and a vessel made of porcelain is called porcelain. Ceramics is a general term for pottery, stoneware and porcelain. All objects made of clay with different properties, such as pottery clay and porcelain clay, can be called ceramics after proportioning, molding, drying and baking.

Second, the main performance characteristics:

1. Ceramic material: Compared with porcelain, ceramics have relatively loose texture and coarse particles. The firing temperature is generally between 900℃~ 1500℃, and the temperature is relatively low. After firing, the color is naturally interesting, simple and elegant, and it has become one of the favorite modeling performance materials for many artists. There are many kinds of pottery, such as black pottery, white pottery, red pottery, gray pottery and yellow pottery. Red pottery, grey pottery and black pottery are made of clay with high iron content. Iron clay is red in oxidizing atmosphere and gray or black in reducing atmosphere.

2. Porcelain material: Compared with pottery, porcelain is hard, fine, forbidden, high temperature resistant and rich in glaze color. The firing temperature is generally around 1300℃. People often describe porcelain as "as bright as a mirror, as bright as Yan Ruyu and as thin as paper". Porcelain gives people the feeling of being noble and gorgeous, which is just the opposite of the simplicity of pottery. Therefore, many artists will emphasize the different sensory enjoyment brought by the texture of pottery or porcelain when creating ceramic works of art. Therefore, it is necessary to analyze and compare the characteristics of two different materials before creation.
