Abstract

A lacquered wooden coffin decorated with gilded Sanskrit letters excavated in the Nongso ancient tomb site was constructed around the fourteenth century in Korea. Pyrolysis/gas chromatography/mass spectrometry was employed to identify the materials of the lacquered surface by analyzing the individual layers. The components of lacquer were detected in all four layers of wood substrate, black, brown, and gilded layers, indicating the coating material was Asian lacquer. The wood seems to be a kind of pine tree from the observation that pine resin-related components were detected in much of the wood substrate and decreasing in the upward direction. Markers of drying oil like azelaic acid and palmitic acid existed in large quantities in the black, brown, and gilded layers, indicating that drying oil was intentionally added to give a luster. In addition, compared with dried Asian lacquer from Korea, the lacquer used in the coffin was determined to be of the same type.
