Towards the end of the 6th or in the early 7th century, Khmer potters instituted an important technique for mass production of ceramics: they began to use the wheel. A Khmer inscription dating to 674 compares the source of creation to a potter’s wheel.
Ceramics of this period were sometimes decorated with slip and paint, but this practice was abandoned after 800 CE 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 CE. It is not known, however, how the process of firing stoneware or the glazing of ceramics appeared in Cambodia.
Khmer ceramics were not exported beyond the Khmer cultural zone.
