North Water Diversion Project, archaeological surveys and excavations were conducted at the Qiaojiayuan village in Yun County by archaeologists from the Institution of Cultural Relics and Archaeology of Hubei Province and other archaeological institutions, revealing a tomb cluster and remarkable artifact assemblages, including elaborately designed and cast bronzes. Since case studies and technical investigations of the ancient bronzes found in northwestern Hubei Province have been rarely reported, and the bronzes of the Warring States Period and the Eastern Han Dynasty excavated from the Qiaojiayuan tombs have not been analyzed technically, the present work endeavored to analyze these bronzes by metallurgical examination and X - ray Fluorescence ( XRF). Samples from 14 bronzes (mostly utilitarian artifacts) in burials at the Qiaojiayuan tomb cluster were collected for this purpose. The results show that 1) Except one inlaid wire of a bronze pot which is Cu-Sn binary alloy with low tin content, all the others are Cu-Sn-Pb bronzes; and 2) the investigated bronzes are mostly cast bronzes, but techniques such as hot and cold forging, metal core support, copper inlay were also used. These preliminary results provided data for further study of the production of bronzes of the Warring States to Eastern Han periods in Hubei.
