Through the detection and imaging using computed tomography (CT), it is found that 1) there are 26 components of the Chen Zhang round pot, instead of the 19 described in the original archaeological report; 2) the body of the sword of Liao (king of Wu) has been seriously corroded and the inscription on the sword was cast rather than engraved afterwards; 3) the state of a bronze plate of the Spring and Autumn Period before its restoration is clearly visible. It can be seen that the CT technology can play a key role in revealing the casting process of ancient bronzes, identifying the authenticity of bronzes, and inspecting the technological routes of conservation and restoration.
