GLOSSARY

Kaolin (Gaoling)

White-firing China clay, an essential ingredient of Chinese porcelain. It consists mainly of silicon oxide and aluminum oxide, with a low content of iron oxide and other metallic oxides. The name derives from that of the Gaoling (High ridge) hills, from where the China clay used at the Jingdezhen kilns was obtained up until the end of the Ming dynasty.
