Towards the end of the 6th or in the early 7th century, Khmer potters instituted an important technique for mass production of ceramics when they began to use the wheel. A Khmer inscription dating to 674 compares the source of creation to the potter’s wheel. Ceramics of this period were sometimes decorated with slip and paint, but this practice was abandoned after 800 when glazed stonewares first appeared.
The first glazed ceramics made in Southeast Asia beyond the orbit of Chinese control were associated with the Khmer rulers Indravarman and Yasovarman, who reigned from the 880s to 940. It is not known, however, how the method of firing stonewares or of glazing appeared in Cambodia.
Khmer ceramics were not exported beyond the Khmer cultural zone.
