The green lotus-shaped lacquer bowl unearthed from a Song Dynasty tomb at Bashi Town of Wuxi is a very rare “dark-green lacquer” object. The green lacquer specimen was analyzed and studied using 3D video microscopy, laser micro-Raman spectrometry (LRS) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The results show that 1) the green lotus-shaped lacquer bowl was made through the processes of body making, plastering and priming, and red and green finish lacquering; 2) the material for the body is Chinese fir (Cunninghamia lanceolata); 3) vegetable oil and Chinese lacquer were used as the binding materials for the plaster while cooked tung oil was added as an auxiliary in Chinese lacquer for the finish. In addition, it is worth noting that cinnabar colors the red lacquer film and a mixture of gamboge and indigo pigments the green one. This study is the first scientific attempt of its kind to identify the production techniques for “dark green lacquer” objects.
