Analysis of Japanese Jomon lacquer-ware by pyrolysis-gas chromatography/mass spectrometry

摘要

Japanese Jomon period lacquer-ware objects were analyzed using a digital optical microscope and pyrol-ysis gas chromatography-mass spectrometry. Comparison with standard lacquer films showed that all the objects were coated with sap tapped from Rhus vernicifera lacquer trees. Red iron oxide was used as a red pigment. Natural resin found in the lacquer pieces suggested that during the development of Japanese Jomon lacquer-ware, lacquer workers used local lacquer resources to produce lacquer, and learned to use natural resin in the restoration and protection of the lacquer-ware objects. In addition, the production and technology of Jomon lacquer-ware are also discussed.
