Wang, Xin published the artcileSystematic study of the material, structure and lacquering techniques of lacquered wooden coffins from the Eastern Regius Tombs of the Qing Dynasty, China, Formula: C23H46O2, the main research area is mercury sulfide lacquered wooden coffin lacquering pigment.
This paper presents a series of detailed anal. results from lacquered wooden coffins of Emperor Qianlong’s concubines (Huixian, Shujia) and second empress (Wulanala) excavated from the Eastern Regius Tombs of the Qing Dynasty, China. The anal. is focused on the materials used in the lacquered wooden coffins, specifically investigating the pigments, lacquers, organic additives and lacquering techniques using digital microscopy, SEM-EDS, XRD, micro-Raman spectroscopy, FT-IR and THM-Py-GC/MS. The results demonstrate that the mineral pigments were mainly HgS, As2S3, the golden area in the lacquer film layers mainly contained elements Au and Ag, the lacquer ash layers mainly included several layers of stucco and fiber layers arranged alternately, the lacquer sap was urushi, and heat-bodied tung oil was also present in the lacquer. Furthermore, several kinds of lacquering techniques, which demonstrated traditional Chinese lacquering and the rigid hierarchy of funerals in feudal dynasties, are also identified in this investigation.
