In the West, the term celadon is often used to describe ceramics covered with green glazes. In China, these wares are generally classified by the names of the kilns in which they were produced, both domestically and for trade. In this example, one of the ghree lively dragons that fill the interior has his tail tucked beneath his hind legs, a design that is characteristic of the Yue kilns active in Zhejiang Province from as early as the second century B.C. Yue wares were widely traded from the eighth to the eleventh century, when work at the kilns ceased. Examples have been found as far west as Africa.
