The Tangyang preserved by the Yangshi Lei family contains rich scientific and artistic value, which is helpful for cross-reference, and comprehensively study the construction system of ancient Chinese architecture from the perspectives of materials, dimensions, styles, and craftsmanship. It can also be used as a reference for ancient architectural design, repair, restoration research, etc. At present, the research of the Tangyang models focus on the interpretation of the relevant historical facts and space of building construction. Relatively speaking, the understanding of Tangyang themselves is not sufficient, in-depth research is still an individual case, and a comprehensive and overall understanding has not yet been formed. Especially in terms of production process, it is still in the preliminary stage of exploration, there is a lack of scientific and systematic in-depth excavation. There are relatively few reports on the scientific analysis of painted pigments in Tangyang samples. There are a wide range of pigments used in the Yuanmingyuan-Tongleyuan Yangshi Lei Tangyang. The recognizable pigments are red, blue, green, white and yellow, which are commonly used in Qing Dynasty architectural painting. Some components fell off from the Tangyang and were scattered around, which need to be resorted. Raman, Micro-FTIR, SEM-EDS and XRD were used to analyze and study the pigments used in the Tangyang. The pigments include both inorganic mineral pigments and organic plant pigments. Researches have shown that the red pigment is cinnabar, the blue pigment is artificial ultramarine, the green pigment is emerald green, the white pigment is calcium carbonate, and the yellow pigment is gamboge. As an organic dye, gamboge is easily degraded by environmental influences. Therefore, it is rare in paper cultural relics. And the research results provide evidence for the application of gamboge in Qing Dynasty paintings. This study also provides an important scientific basis for a detailed understanding of the information status of cultural relics such as materials and processes.
