In order to provide a scientific basis for the conservation and restoration of the bronze beast-face decorations unearthed in Chenggu County, Shaanxi Province, and to further reveal the production techniques and related archaeological information, five bronze beast-face decorations were analyzed, non-destructively, using X-ray inspection, hyper-depth-of-field microscopy, X-ray fluorescence (XRF) spectrometry and Raman spectrometry. The results show that two of them are tin bronze and the other three are lead-tin bronze. The corrosion objects on the surface of them are dominated by CuCO₃·Cu(OH)₂, Fe₂O₃, lepidocrocite γ-FeOOH and CaCO₃ in some areas. In addition, their processes of casting, traces of re-casting, proportion of copper materials and the process of production of small holes are discussed. These bronze beast-face decorations are also compared with the same types of artifacts unearthed at Yin Ruins and Laoniupo. It is concluded that the craftsmanship and style of these bronze beast-face decorations are consistent with those of other bronzes in this area. This information provides a data basis for understanding the “Chengyang Bronze Group” from the perspective of materials and craftsmanship.
