Abstract

In this paper, pulsed infrared thermography is applied to the study of an ancient Chinese bronze sword. A clay core, as a piece-mold casting remains, is found inside the sword handle, the length of which is obtained by analyzing the thermographic images. Meanwhile, corrosion and cracks are also located on the body of the bronze sword. To obtain the thickness of the bronze handle around the clay core, thermal quadrupole simulation is used. By analyzing the characteristic time from the thermographic experiment and the simulation, the thickness of the materials is determined. These results provide a deeper understanding of the manufacturing of the bronze sword and also contribute to the later conservation studies.
