School of Archaeology and Museology Peking University Beijing China AbstractIn order to explore the history and technology of lacquer manufacture in Chengdua batch of painted pottery objects unearthed in the first session of archaeological excavation the Xinyicun Site of Shierqiao district in Chengdu in 2010 were analyzed via radiocarbon dating through accelerator mass spectrometry AMS- 14 C Fourier Transform Infrared Spectroscopy FTIR Optical Microscopy OM Micro Laser Raman Spectroscopy Micro- Ramanand X-Ray Fluorescence XRF. The results of these studies showed these objects were probably used during from middle or late Western Zhou Dynasty to the Spring and Autumn period. The pottery was made of fusible clay the black and red painting layers were Chinese lacquer mixed with carbon black and cinnabar HgS respectively. A layer of black lacquer was brushed on the whole surface of the pottery first and then the red paint was used to outline the pattern. These discoveries suggest that the lacquer craftsmanship in the Chengdu Plain can be dated back at least as far as the middle or late Western Zhou Dynasty.
