Twenty-two gilt metal objects and gold and silver wares dating back to the Northern Qi Dynasty were unearthed from the Han Zunian Tomb in Taiyuan, Shanxi Province in 1982. I used microscopy and X-ray fluorescence, two nondestructive methods, to study these relics. I found that (1) the gilt bronzes were formed by casting and then were surface-treated using heated gold amalgam and (2) the technology and the style of the gold and silver wares were influenced by the cultures of Xiyu (or the Western Regions, including what is now Xinjiang and parts of Central Asia). The research results provide important scientific information for the comprehensive understanding and further study of metal-ware technologies of the Northern Qi Dynasty.
