7. Manufacture of Vases (Cho chi)

"The vases and sacrificial vessels, called p'ing, lei, tsun, and yi, are comprised in this general name of cho ch'i. The plain round vases are fashioned upon the potter's wheel, in the same manner as the ordinary round ware; they are then dried in the open air and turned on the polishing wheel to be finished with the knife.

After the vase has been thus shaped it is washed with a large goat's-hair brush dipped in water, till the surface is perfectly bright and spotlessly clean. After this the glaze is blown on, it is fired in the kiln, and comes out a piece of white porcelain. If painted in cobalt on the paste and then covered with glaze, it is apiece decorated in blue.

In making the carved polygonal, ribbed, and fluted vases, the paste, wrapped in cotton cloth, is pressed with flat boards into thin slabs, which are cut with a knife into sections. The pieces are joined together by some of the original paste diluted with water.

There is another kind of vase which is made by the process of molding, and which is finished after it is taken from the mold in the same way.

The carved polygonal vases and the carved molded vases have to be filled in and washed clean with the brush in the same way as the round vases turned upon the wheel.

All the varied forms of vases may be engraved with the style, or embossed in relief, or carved in openwork designs, for which purposes, when sufficiently dried, they are given to artificers specially devoted to these several branches of work."

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
