Bronze inlaying craft was a superb technique for surface modification of bronzeware. For its technological characteristics and process, the academia had a more complete speculation, but there was no example to prove. By means of observation, metallographic analysis and SEM-EDS analysis, the morphological, structural and component characteristics of copper inlaying into bronze beans unearthed were explored in Huairou, Beijing, and the surface decoration process logic was deduced. The results show that the body of the bronze ware is firstly made and the chisel is used to carve the groove on the surface of the bronze ware after casting. Red copper wire or copper plate is used to make the decoration, and repeated hot forging is carried out to make the decoration basically conform to the shape of bronze groove, and then it is directly hammered into the bronze matrix. In order to provide a scientific basis for the protection and restoration of bronze inlaying ware, this study is conducted to enhance the understanding of bronze inlaying ware.
