Ban Nong Chik (Kra Chai) is a village in Ban Kruat distict, Buriram province near the Thai - Cambodia border. It was historically in the western Angkorian territory. This archaeological site was recorded during the survey of Ban Kruat District by Living Angkor Road Project (LARP) in 2006 (Lertlum et al., 2008). Previous excavations at the sites of Ban Khao Din Tai and Sai Tho 7 demonstrated that the iron production traditions of Ban Kruat relied on a smelting process operated in a shaft furnace using local lateritic ores. Accelerator Mass Spectrometry (AMS) results indicated an Iron Age date for Say Tho 7. Archaeological excavations at Ban Nong Chik were aimed at building on previous archaeological studies in Ban Kruat studies. At Nong Chik, waste from two different manufacturing activities was recorded; these are pottery production and iron smelting. Artifacts from the iron smelting process included clay plugs, furnace fragments, tuyères, clay sphere setters and stoneware sherds, and were all found within the same cultural layer. The fifteen samples analysed using optical microscopy and handheld X-ray fluorescence suggests that the smelting operation was conducted at reachable temperatures between 1150˚C and 1300˚C. All the slags fall into the iron poor eutectic category, and hercynite, due to high level of alumina (approximately 10 - 11wt%). The fact that the iron producers were able to utilise low quality ore shows they had a good understanding of how to efficiently smelt relatively-high-alumina ore. Radiocarbon dating (AMS) of two samples (organic sediments) in cultural layer 1 produced dates in the 13th - 14th century CE, bringing the site into lime with the closest known pottery kiln at Burirum (Nai Jian kiln), which dates to the 10th - 13th century CE. This new dating from Ban Nog Chik site is important evidence that suggests iron smelting in Ban Kruat district can be traced from the Angkorian Khmer Empire to the Ayutthaya period (13th - 14th century CE).
