Abstract：Spectroscopy is the use of light on the interaction of substances, providing the microstructure of substances and different chemical analysis methods to achieve the quantitative and qualitative substances. A large number of spectral analysis techniques are used in the process of making murals. In this study, taking Huapen Guandi Temple of Yanqing in Beijing as an example, the techniques and materials formaking murals are analyzed by spectral analysis and other techniques. Huapen Guandi Temple is located in Huapen village, Yanqing District, Beijing. It was built in the fourth year of the Yongzheng reign (1726) of the Qing dynasty. Many spectral analysis techniques are used in the process analysis of mural making. This study takes Beijing Yanqing Huapen Guandi Temple as an example to analyze the mural making process and materials. Using a range of spectroscopic techniques, including X-ray diffraction, Raman spectroscopy and laser particle size analyzer, the study found that the mural of Guandi Temple is supported by an adobe wall. The main components of the ground layer are quartz, calcite and albite, and the main components of the white powder layer are gypsum. The red pigments in the pigment layer are iron red, lead and cinnabar. Blue is azurite, yellow is chrome yellow, black is carbon black, white is gypsum, green is Paris green, green earth and chrome green. The Binder of gold coating with pitch powder is cooked tung oil and rosin resin, and the gold foil is red gold with a gold content of 86.1%.The Raman spectrum can not only distinguish the pigment of the fresco but also prove it through the research of the pigment history and enrich the historical information of the fresco. It is of great significance to study and protect the ancient frescoes by combining the spectral analysis data of cultural relics with the literature data and fully excavating the information behind the cultural relics. Through the difference in the making technology of the wall of the same wall in Guandi Temple, this paper shows that the material and the craft of the mural are affected by the position. It is expected that the researchers will find the typical cases of murals by the regulations by studying the differences of murals making materials and techniques and summarizing the regulations of murals making in past dynasties.
