China is one of the few ancient civilizations in the world with a long history and has made many significant contributions to the progress and development of human society, including the famous and famous Chinese porcelain. Achievements in the field of ceramic technology and art are of particular importance. In China, the emergence of pottery art dates back to the period between 4500 and 2500 BC. It can be said that an important part of China's development history is the history of ceramics. The achievements of the Chinese in the fields of science and technology, as well as the pursuit and shaping of beauty, have been reflected in many ways in the manufacture of ceramics, and have formed the very typical technical and artistic characteristics of each era. More than a thousand years before Europe mastered the art of porcelain making, China was already capable of producing quite fine porcelain. In the history of Chinese ceramics, the term "ceramics" is generally divided into two categories: pottery and porcelain. In general, the paste is not densely sintered. Clay and porcelain products, whether colored or white, are collectively called pottery. Among them, the firing temperature is higher, the degree of sintering is better; this part is called "hard pottery", the glazed part "enameled pottery". Relatively speaking, after high temperature firing, the degree of sintering of the paste is more dense, the glaze quality of clay or porcelain stone products is called "porcelain". The development of traditional Chinese ceramics has gone through a fairly long historical period, with a wide variety of types and special techniques, so the classification of traditional Chinese ceramics requires a comprehensive examination of the usual traditional classification methods, in addition to the technically rigid indicators, and changes in scientific and technological understanding between ancient and modern times, in order to draw more effective conclusions about classification. Tang Sancai porcelain is inextricably linked to earthenware. When a partial mixture of kaolin (or natural glazes such as feldspar, quartz and lime) and other raw materials containing natural colored components such as copper oxide, iron oxide and Lead oxide is used in the firing of pottery, a fine glaze naturally forms on the surface of the pottery (this is how Sancai first appeared in the category of Japanese Shinra-yaki pottery). Prior to the Ming Dynasty, Chinese porcelain was mostly plain porcelain. After the Ming Dynasty, painted porcelain was the main popular porcelain. Japan, another porcelain producing country, has also developed its own tea ware with the tea ceremony culture. The oldest plain porcelain was classified according to color, with celadon, black porcelain and white porcelain in three common colors Painted porcelain and other colored porcelain are more famous: Tang Sancai (Tang Sancai is not of the porcelain, it is a low-temperature lead pottery), Shinraku, celadon, etc. There are also different classifications depending on where the porcelain is produced. In China, the Yue kilns in Zhejiang (secret porcelain), Changnan in Jiangxi, Ding porcelain in Hebei and the characteristic porcelains developed in Japan after the 10th century: Shigarakiyaki from Omi and Koga, Aritayaki from Nagasaki , the Bizenyaki of Okayama Prefecture, etc.
