Abstract:Subhash Buddhist temple in Kuche, Xinjiang, is an important site on the Silk Road in ancient China. The study of relics at this site is of great significance to understanding region culture and communication with surroundings. A batch of copper wares lately discovered at the site can be divided into weapons, ornaments and living appliances according to shape, and X ray fluorescence spectrometer is used to analyze their chemical composition. The results show that copper wares are of various types including lead tin bronze, red copper and brass. With historical and archaeological resources analysis, the Buddhist ornaments of brass are from Buddhist culture transmission, and living appliances are brought into through trading with central plains dynasty. The wares bearing arsenic and antimony elements may come from local trade in Xinjiang, and the red copper and bronze wares may be produced locally. The comprehensive analysis shows that Subhash Buddhist temple area at that time not only had its own metal manufacture, but also served as an important role for frequent exchange culture and material with surroundings along Silk Road during Tang Dynasty.
