The Plain of jars remains an enigmatic and striking element the prehistoric landscape of Laos. The production of the thousands of megalithic jars spread predominantly across the Xiang Khouang Province (but also the Hua Phan and Luang Prabang provinces) remains a highly fascinating yet mysterious phenomenon. Current archaeological literature supposes Iron Age associations for jar production and use. These associations were initially based upon artefactual finds ubiquitous with the regional Iron Age and identification of tool marks as those of iron tools reported in the 1930’s. More recent research has provided a range of dating through the use of Radiocarbon dating and Optically Stimulated Luminescence (OSL) which ranges greatly from 1240 BCE through to the late 13th century CE. While this broad range exists much of the work highlights the later dating, conforming to a narrative of Iron Age production. In this presentation, I will explore the validity of the suggestion of iron tool use and further explore the continued influence this suggestion has imposed on the resulting academic narrative of the Plain of Jars. This exploration is performed through the lens of experimental (re)construction, emphasising the capability of different tool materials, their effect on the outcomes of the experimental works, and provide an estimation of time investment for jar production. Additionally, the research provides insights into the material consequences of jar production in the hopes of aiding the identification of jar manufacturing locations.
