In this study, seven excavated bronze artifacts were examined using optical microscopy, SEM-EDS, and Raman microspectroscopy to investigate the distribution characteristics of corrosion products. Based on the stratigraphic structure of the corrosion layers and the presence, absence, and morphology of the outer corrosion layer, the corrosion patterns were subdivided into Groups A–D. These groups were then compared with the corrosion types proposed by L. Robbiola and Omid Oudbashi, allowing the establishment of a more refined morphological classification system. In addition, the distribution of corrosion products was analyzed in relation to Cu–Sn and Cu–Sn–Pb alloy phases. The results demonstrate that corrosion morphology varies according to manufacturing techniques and alloy composition, and that different groups may coexist within a single artifact, indicating that variations in burial environment can also influence the corrosion form. These findings provide fundamental data for the comparative interpretation of corrosion patterns in excavated bronze artifacts and for future studies in conservation science
