Khmer Crafts, Materials and Production

Across the Khmer Empire, whose capital region lay around Angkor in present-day Cambodia, craft production from roughly the ninth to fifteenth centuries depended on local materials, trained hands and repeated processes. Archaeological remains from kilns and workshops show how makers fired jars and prepared bronze; plant remains and a visitor’s account reveal how cotton fiber became cloth. Dated inscriptions also connect skilled workers and their products with temple foundations.

Kilns, jars and firing

Potters fired clay as earthenware, which needs less heat, or as stoneware, a harder ceramic that needs more sustained heat. At Chong Samrong in Siem Reap province, a 2013 excavation documented a kiln used for brown-glazed stoneware. The excavation report describes three successive kilns built into one mound. Each later firing chamber sat inside and slightly above its predecessor, allowing its makers to reuse much of the earlier chamber base and firebox.

A fire trench ran across the firing chamber, while four apertures in the far vent wall carried hot exhaust gases out. As the kiln was rebuilt higher, workers extended the trench walls to serve the raised chamber. These features show how kiln architecture guided heat through a load of large jars. Brown or black glaze fused onto the stoneware surface during firing; some jars instead collapsed and fused together. Other fragments were intended as stoneware but remained underfired, with immature glaze still on the outside. The failed vessels preserve the risks of controlling a large kiln’s heat.

Metal supply and bronze casting

Near Angkor’s royal palace, a foundry active during the eleventh century occupied a work area smaller than one hectare. Excavators found hearths and floors with waste from melting and shaping metal, as well as moulds and furnace-wall pieces. These remains trace successive steps rather than one act of casting. Metal reached the workshop as fresh copper and tin ingots, or as old objects to melt again. An ingot is a shaped bar of metal. Workers could refine the metal, combine copper and tin into bronze, then store prepared alloy as new ingots before casting.

The Angkor foundry excavation documents lost-wax casting: a maker shaped a wax model with channels for pouring, surrounded it with a heat-resistant clay mould, then melted out the wax and poured in molten metal. Clay mixed with rice husks formed moulds and furnace parts; charcoal supplied heat. After casting, workers could join separately made pieces, polish surfaces or apply gilding, a thin layer of gold. The same workshop area also shows copper hammered into shape, a different technique that did not require pouring molten metal into a mould. Foundry debris and unfinished objects reveal practical stages of skilled production.

Cotton fiber, looms and temple work

Cotton seeds and fragments of their attachment stalks found at Angkor Wat and Ta Prohm indicate that cotton bolls, the plant’s seed-containing fruits, reached those enclosures. The lint around each seed could be separated into fiber, leaving seeds as processing waste. The archaeobotanical study by Castillo and colleagues interprets the finds as evidence that some cotton preparation took place at the sites. In sampled eighth- to tenth-century layers at Ta Prohm, before the temple was built, cotton forms 74 percent of the identified economic-crop assemblage; it appears in later occupation phases too.

Zhou Daguan, who visited Angkor in 1296–1297, described cotton yarn wound by hand and a body-tension loom. The weaver stretched the warp, the lengthwise threads, fastening one end to a belt around the waist and keeping the other under tension. A short piece of bamboo passed through these threads as a shuttle, carrying the crosswise yarn that binds the cloth.

Inscriptions connect skilled work with temple service and supply. A 1025 inscription associates rice fields with cooks, musicians and workers described as leaf weavers. A late-twelfth-century Ta Prohm record names a weaver’s shop alongside villages and a market as sources of clothing and produce. Together, these references show distinct ways that temple foundations drew on skilled labor and textile goods, while kiln and foundry remains document other forms of production in the Angkorian economy.
