Abstract:Five Minerals are frequently found in Han Dynasty tombs. However, research on their chemical composition remains limited, with few studies providing detailed analyses of their specific components. This study presents a comprehensive chemical characterization of Five Minerals samples collected from a vase inscribed with cinnabar found in Tomb M3300. The analytical methods employed include optical microscopy (OM), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Fourier-transform infrared spectroscopy (FTIR), and Raman spectroscopy (RM). The results indicate that the blue-colored minerals are primarily composed of azurite. At the same time, the red-colored minerals consist predominantly of realgar, which can degrade into uzonite and arsenolite. The black minerals are high-purity magnetite; the white minerals are dolomite with trace amounts of quartz; and the gray minerals are mica. This is the first scientific identification of dolomite and mica as key components of the Five Minerals. Furthermore, the inscriptions and Taoist symbols on the vase indicate that the Five Minerals served as protective agents for the tomb rather than for medicinal use. Although literary sources from the Han Dynasty offer specific references to the Five Minerals, a mixture of Cengqing, Dansha, Baiyu, Xionghuang, and Cishi. Their application in tomb protection is more closely associated with their color, physical properties, and symbolic meanings than with their precise chemical composition. This results in a certain degree of variability in the chemical makeup of the Five Minerals. The findings of this study significantly contribute to our understanding of both the material properties and the ritualistic functions of the Five Minerals in Han Dynasty burial practices.
