抄録
Infrared spectroscopic analysis and radiocarbon dating by accelerator mass spectrometry (AMS) were conducted on black material filled in the bottom of hasō, collected at the Shindate site, Higashihiroshima. The black material is shiny black, accompanied by sand, gravel, and plant remains, and was viscous when the sample was taken. Infrared spectroscopic analysis showed apparent absorption of hydrocarbons and the absorption of urushiol, which characterizes raw lacquer. The black material is identified as lacquer. The age ranges obtained by calibration of the 14C ages were 606-626 cal AD (45.46%) and 636-646 cal AD (22.81%) in the 1σ calendar year range and 600-651 cal AD (95.45%) in the 2σ calendar year range. The carbon dating results are consistent with hasō, which contains lacquer.
