摘要
A lacquer inkslab is a special kind of inkslab. Both the lacquer wood inkslab and the lacquer sand inkslab are examples of it and show diffrent technological characteristics. In the early stages, the lacquering process of lacquer inkslab was relatively simple, but in the Ming and Qing Dynasties, the lacquer sand inkslab reached the peak of its development. We carried out research on a lacquer inkslab unearthed from the tomb of Zhu Ran of the Three Kingdoms Period using micro computed tomography ( CT), Raman and infrared spectrometry, etc., to explore the ancient lacquer inkslab technology. The results show that the lacquer was applied directly on the wooden body, that the exterior color of the inkslab hall and the inkslab box is the natural color of the lacquer, and that the red pigment on the edge of the inkslab hall is cinnabar. No abrasive particles, such as emery or quartz powder, were found in the lacquer layer of the inkslab hall. The inkslab was recorded as a "lacquer sand inkslab'' in the archaeological report; however, the technology of lacquer sand inkslab can be found only in documents of the Ming and Qing Dynasties, and typically the inkslab hall is composed of lacquer and abrasive particles. Therefore, more suitably, the inkslab from the tomb of Zhu Ran should be called a lacquer inkslab. The experimental results of this research could provide a reference for the study of inkslabs of the two Han Dynasties.
