Abstract: The oldering technique of Bronzes Excavated from Jiuliandun Tomb of Warring States in Chinese Hubei Province was investigated.According to naked-eye observation, it was concluded the welded splice used mortise-tenons, with smooth and crinkly soldered joint by thermal processing and that the pouring gates were designed at the bottom or the side wall.The solders were investigated using diffraction, X-ray fluorescence, scanning electron microscopy with energy dispersive X-ray detection and differential scanning calorimetry.Results show that solders were composed of Pb-Sn alloys with average mixture ration about Pb73 and Sn27 by XRF analy sis, and the phase was as-cast microstructure observed by SEM, which indicated ancient people poured melting solder to connect different bronze parts, and the melting point of some solders existing in 180-186℃ by DSC, which meant they had low work temperature and the aim to produce them just were used as bronze sacrificial ware.
