Abstract:The hoof-shaped ingots unearthed from the tomb of Marquis Haihun are very important with regard to the study of gold coinage during the Han dynasty. There are inlaid ornamentations in each hoof-shaped ingot, most of which have been seriously corroded.In order to identify the inlay materials in the hoof-shaped ingots, we used polarized light microscopy (PLM), backscatter scanning electron microscopy-energy dispersive spectrometry (BSE-EDS), infrared spectrometry (IR) and X-ray diffraction (XRD) to study the samples. The results reveal that the inlaid ornamentations can be classified into four types:tremolite, opal, lead-barium glass and lead silicate glass. The glassy state of lead-barium glass is basically preserved, and the corrosion products have recrystallized due to the changes of the burial environment, eventually becoming lead carbonate. However, the corrosion of lead silicate glass is entirely different in that the exterior with higher siliceous component has formed a compact shell, with the botryoidal (grape cluster-like) lead carbonate filled in the cavity of the small amount of silica inside the shell. The study could provide a theoretical support for the subsequent restoration of hoof-shaped ingots.
