Radiocarbon dates from recent excavations of a range of Angkorian Khmer (~9th-14th CE) stoneware kiln complexes provide a new and independent perspective on the timing and geography of Khmer ceramic production. These data demonstrate a clear two-phase sequence. The first, in the late 9th to late 12th centuries CE, marks a period of intensive production located both to the east of Angkor and to the south at Cheung Ek, south of Phnom Penh. A second shorter phase of production occurred in the late 13th to late 14th CE at more distant provincial settings following the collapse of the Angkorian state.
