Alumina Ceramics:
Alumina ceramics is a general term for pottery and porcelain. Vessels made of inorganic mixtures of pottery clay and porcelain clay (kaolin) as raw materials, molding, drying, and baking are collectively called ceramics. Since ancient times, the handicraft industry specialized in making pottery and porcelain was called ceramic handicraft. The history of Chinese pottery production is very long. Pottery born more than 10,000 years ago were found at the Nanzhuangtou site in Xushui County, Hebei Province; the Shenxian Cave site in Huifeng Mountain, Laishui County, Jiangsu Province has unearthed pottery pieces about 11,000 years ago. A large number of red, gray, black, white, painted, and painted pottery have appeared in the Neolithic culture in China since 8000 years ago. After entering a class society, red ceramics, gray ceramics, polished black ceramics, painted ceramics, and various types of ceramic art and architectural ceramic components reflecting the real life of society were produced in large quantities. The lead glaze pottery was invented during the Warring States Period, and pottery products were beautified with low-temperature colored glaze. The mass production of three-color glazed pottery in the Tang Dynasty reflected the appearance of the Tang Dynasty and was highly artistic. After the Song Dynasty, the production of glazed pottery was gradually reduced, and the production of glazed building elements was switched. Because porcelain is widely used in social life, the production of pottery is increasingly fed but never stopped. Porcelain began to appear in the middle of the Shang Dynasty. The earliest porcelain was celadon. Due to immature technology, it is also called primitive celadon. The Han Dynasty celadon firing gradually matured, getting rid of the original state and entering the early porcelain stage. Black porcelain began to appear in the Han Dynasty. During the period of the Three Kingdoms, the Northern and Southern Dynasties, southern celadon developed extensively, forming a unique system.
