Ceramics are the most abundant types of artifacts made by human beings in the last 12,000 years. Chinese potters discern two types of products: earthenware (tao), which is porous and does not resonate when struck, and wares with vitreous bodies (ci), which ring like a bell. Western potters and scholars differentiate stoneware, which is semi-porous, from porcelain, which is completely vitrified.
The earliest ceramics in the world are thought to have been made in China around 15,000 years ago. By the Shang dynasty, potters in China began to decorate the surfaces of their pottery with ash glaze, in which wood ash mixed with feldspar in clay to impart a shiny surface to the pottery. The first ash-glazed wares were probably made south of the Yangzi in Jiangnan.
In the 9th century, China began to export pottery, which quickly became sought after in maritime Asia and Africa. Pottery making for export became a major industry in China, employing hundreds of thousands of people, and stimulating the development of the first mass-production techniques in the world. Much of the ceramic industry was located along China’s south and southeast coasts, conveniently located near ports that connected China with international markets. Chinese merchants had to adapt their wares to suit different consumers. For the last 1,000 years, Chinese ceramics provided an enormous amount of archaeological information on trade and society in the lands bordering the South China Sea and the Indian Ocean, contributing a major source of data to the study of early long-distance commerce, art, technology, urbanization, and many other topics. Statistics are presented from important sites outside China where Chinese ceramics have been found.
