6. Fashioning the Round Ware on the Wheel

"There are several different processes of work in the manufacture of this round ware. The square, polygonal, and ribbed pieces, and those with projecting corners, have to be carved, engraved, molded, and finished with the polishing knife, all of which are different branches of work.

The plain round pieces are turned on the wheel, being distributed according to their size between two classes of workmen. The first take the large pieces and fashion the round dishes (p'an), the bowls (wan), the cups (chung), and the saucer-plates (tieh), from one up to two or three feet in diameter; the second make on the wheel the same kind of pieces which measure less than a foot across.

The wheel consists of a disk of wood mounted below upon a perpendicular axle, so as to revolve continuously for a long time, during which the piece must be properly turned, without becoming too thick, too thin, flattened, or otherwise misshapen. There is a carpenter at hand to repair it when necessary.

Beside the wheel is an attendant workman, who kneads the paste to a proper consistency and puts it on the table. The potter sits upon the border of the framework and turns the wheel with a bamboo staff.

While the wheel is spinning round he works the paste with both hands; it follows the hands, lengthening or shortening, contracting or widening, in a succession of shapes.

It is in this way that the round ware is fashioned so that it varies not a hair's breadth in size."

Page credit and sources
This page is based on an English translation by S. W. Bushell, first published in 1899, of a Chinese text compiled under imperial command in 1743. The author was Tang Ying, the superintendent of imperial porcelain production in Jiangxi. The text has been widely reprinted in later literature. The version generally regarded as the most authoritative is preserved in the Provincial Annals of Jiangxi (Jiangxi tongzhi), Book 93, folios 19 to 23. An earlier draft appears to have been written around 1735. In 1743, the text was incorporated into a set described as the “Twenty Illustrations of the Manufacture of Porcelain,” compiled under imperial auspices. The original illustrations associated with this set have not been securely identified. The present page is edited to more modern language in 2025, and illustrated with photographs taken on site in Jingdezhen in 1991 and 1992, by Jan-Erik Nilsson
