This paper discusses the entire process of conservation and restoration of the Han Dynasty jade wares unearthed from the Mizhi County of Shaanxi Province. New methods were used for extraction of information. We discuss the close relationship between on-site conservation and laboratory archaeology in terms of problems that can be avoided in future work. It is emphasized that cooperation among different professional teams is needed to complete different phases of the entire archaeological process. The participation of conservation professionals is needed not only for pre-conservation aspects but also for selection of the right on-site protection methods, so that more archaeological information can be extracted for future research.
