Lao shares common borders with China, Myanmar, Vietnam, Thailand and Cambodia, all of which have been fairy well researched. The history of ceramic production and trading in these countries is already quite well understood yet, little is known about production and trade of ceramics in Lao, especially during Lao’s historical period. In comparison to its neighboring countries, years of conflict and political unrest in the Lao PDR severely restricted field research. Over the last few decades the country began to open up and is now subject to quite rapid development. As Lao began to open its doors it gradually became possible to undertake archaeological excavation and survey. Over the last decade several archaeological surveys have been implemented. Today, as a result of recent archaeological field projects, Laos’ vital link to other countries is becoming progressively clearer. In the attempt to reconstruct past human activity the analyses of ceramic trade, distribution, and production is most revealing. The MMG-LXML Sepon Mining Tenement Site is situated in Vilabouly District, Savannakhet Province in the southeast of the Lao P.D.R. The mining tenement is located in the mountains of Truong Son Cordillera, which runs north-south along the border between Lao and Vietnam. In 2007, a Memorandum of Understanding was signed between the Department of Heritage (Ministry of Information, Culture and Tourism, Lao PDR), MMG-LXML (an internationally-based mining operation) and James Cook University (Australia) in order to cooperate to manage and investigate archaeological heritage within the current MMG-LXML mining tenement. Subsequently more than ten extensive excavation projects have been undertaken, beginning in 2008 and ongoing, with the 47 archaeological sites grouped together as the “Vilabouly Complex” (Tucci et al. 2014). The complex has gained considerable notoriety upon the discovery of hundreds, if not thousands, of artifacts from various periods of history. One of the most dramatic finds recovered was a large bronze drum estimated to be 2,000 years old. Excavations at several sites have also revealed hundreds of extremely well preserved bamboo and hardwood structures integral to mining shafts dated to between 1000 BC and AD 700 (Chang et al. 2014: 191). Other significant finds associated with these remains such as burials containing grave goods, crucibles, wooden mining tools, copper alloy axes, ingots and woven bamboo baskets are fine examples of Lao’s “pre-historic period”, the Iron Age and older. There is now good evidence of Bronze Age mining at sites as well as significant numbers of older Neolithic stone tools. During excavations at the Sepon mining tenement another significant layer of history began to emerge as ceramic products in large quantities from a more recent period began to be revealed. Most of these historical period artifacts were recovered by chance in accordance with stringent UXO (unexploded ordnance) bomb clearance operations. What is particularly interesting to note is that these ceramic collections included an unexpected amount of trade ceramic. That is to say, these ceramics were imported items that were produced abroad. It now appears that these ceramics were imported to the Sepon region over several centuries during Lao’s historical period known as the Lane Xang Kingdom that existed from the 14th century until 19th century. Most of this collection of trade ceramics is currently stored on-site at the mining tenement’s Cultural Heritage Unit Workshop awaiting further conservation and analyses. The lead author’s first opportunity to visit the tenement and examine recovered ceramics was in September 2011. During this visit, a collection of some 15 significant finds was observed. A second opportunity to visit was made available in October to November 2014 and during this visit, a further 67 pieces of ceramic were documented and observed. This brief paper focuses on the preliminary observations of some 82 specimens of “trade ceramic”. It details the examination of their context, composition, characteristics and chronology through comparative analysis with previous research in the Lao PDR, such as the Vientiane Road No.1 survey which was undertaken in the central district in the nation’s capital, Vientiane, by Japan’s Grant Aid Assistance during 2006 and 2007(1). 1. Overview of the Recovered Trade Ceramics Observed The trade ceramic collection considered here totals 82 pieces which were observed to be from various origins. Each specimen can be classified into four categories based on their place of manufacture. For instance, the collection included 68 pieces of Chinese ceramic, ten pieces of Vietnamese, two pieces of Siamese and two pieces of Japanese porcelain. Before this study, it was almost unthinkable to expect that Japanese ceramic products would be recovered in this very remote region, high in the mountains of Laos. It is this finding that is considered to be of exceptional significance. It is also of special interest that the Japanese ceramics were found in combination with Chinese, Vietnamese and Siamese wares. It provides new archaeological insights into the historical Lane Xang era in the Sepon area, in terms of foreign trade. In the following sections, the attributes and characteristics of the specimens will be explained contextually based on place of manufacture. 2. Chinese Ceramics The majority of the collection, approximately 83% are porcelain and stoneware of Chinese origin. The production kiln(s) of each specimen can be identified as one of three kiln sites or regions, namely: 13 pieces are products of Jingdezhen kiln complex in Jiangxi province (i.e. Figs.3-8), 20 pieces are products of Zhangzhou kiln in Fujian province (i.e. Figs. 9-16) and the remaining 35 pieces are products of other anonymous kilns in Fujian or Guangdong provinces (i.e. Figs. 17-23). Jingdezhen and Zhangzhou, are both well known, large-scale kiln complexes that produced huge amounts of Chinese ceramic for export. Jingdezhen porcelain was exported to the whole of Asia, Europe and Africa over the last millennia, while Zhangzhou kiln ware was exported exclusively to Asia. Products from both these major kiln complexes have been recovered from many sites across Mainland Southeast Asia. In addition, it is especially interesting to note that hundreds or thousands of Jingdezhen and Zhangzhou kiln products were also recovered in Vientiane during the Road No.1 survey of 2006 and 2007(2). Aside from the Jingdezhen and Zhangzhou kiln products there remains the 35 pieces that cannot be positively identified to their exact production kiln at this time. These 35 specimens can only be classified as products of minor kilns in Fujian and/or Guangdong provinces. Historically, over the last millennium, numerous kiln sites were spread across both provinces, some of which had exported 48 ceramics to the whole of Asia and beyond since ancient times. For instance, the Dehua kiln in Fujian and Xicun kiln in Guangdong are well researched and documented. Most of the finds from the Sepon mining operation sites however, were produced in other miscellaneous kilns, which produced and exported ceramics around the time of the Qing dynasty. Categories The
