- preliminary research on the polychrome clay sculptures and murals in the Du Le Temple, stage I (Shaanxi Provincial Institute for the Conservation of Cultural Heritage)
This study systematically analyzed the mineral pigments, adhesives, and painting techniques of the Eleven-Faced Guanyin statue in Tianjin, China during the Liao Dynasty, revealing the composition of pigments and types of adhesives used in different color areas, as well as the presence of gilding technique in the gold areas.
This article aims to systematically and comprehensively analyze the mineral pigments, adhesives and painting techniques of the Eleven-Faced Guanyin of the Du Le Temple in Tianjin, Liao Dynasty, China. Digital microscopy, FESEM-EDS, XRD, micro-Raman spectroscopy, FT-IR and THM-Py-GC/MS scientific microdestructive or nondestructive methods were selected for in-depth study. The investigation shows that the mineral pigments principally contained black (carbon), red (minium or cinnabar), orange (minium and litharge (tetragonal PbO)), blue (ultramarine blue and blue sodalite), green (atacamite), cyan (malachite) and gold (mainly referring to Au and Ag powders). Furthermore, adhesives used in the gold areas were heat-bodied tung oil, while adhesives used in other color areas were glue-protein. Additionally, during the study of the painting techniques, gilding technique was also found in the gold areas.
