為了解陜西橫山縣高鎮羅圪臺元代壁畫工藝和顏料成分,采用偏光顯微分析、剖面分析、顯微拉曼光譜和巖相分析對13個樣品進行分析。結果表明,其繪制方法是先用加有植物纖維的粘土將墓室壁畫抹平,然后用石灰涂白,再施以彩繪。所使用的顏料為礦物顏料,多為藍、紅、黃、綠、白、黑色等。其藍色顏料為石青、紅色顏料為鐵紅和朱砂、黃色顏料為鐵黃、綠色顏料為氯銅礦和石綠、白色顏料為碳酸鈣以及黑色顏料為墨。

In order to investigate the technology and pigments employed for painting the murals in a Yuan Dynasty tomb discovered in Luoqitai, Shannxi Province, 13 samples were studied via polarization microscope observation, Raman spectral analysis, thin section examination, and petrographic examination. According to the results, the painting procedure of the murals was as follows. First, the surface was smoothed by adding clay mixed with plant fiber. Then a layer of lime was applied, and on the top was the color layer with pigments. Results show that the blue pigment was made of azurite; the red pigment was made of iron oxide and cinnabar; the yellow pigment was made of yellow iron oxide material; the green pigment was made of copper chloride and malachite; the white pigment was made of calcium carbonate and the black was of black carbon.
