Scientific Analysis, Conservation and Restoration on the Cultural Relics Golden Gourd-Shape Hanging Screens with Auspicious Pattern from Qing Dynasty in the Palace Museum

The Palace Museum has a group of eight collections of cultural relics named golden gourd-shape hanging screens with auspicious patterns from Qing Dynasty. In this study, two of them were used as the cultural relics protection and restoration samples (故11214 and 故11703). During restoration, there were dust stains on the surface and many inserts were loose or missing. In order to restore the integrity and beauty of the cultural relics, the relevant measures need to be taken to protect and repair them. First, the types and cause of the disease of golden gourd-shape hanging screens with auspicious patterns were understood.Then, all the inlaid gemstone materials in the hanging screens were tested by Raman spectrometer. The results show that there are gems such as coral, spinel, tourmaline, aquamarine, jadeite, lapis lazuli, turquoise in the repaire area.The metal compositions of the hanging screens were detected by X-ray fluorescence spectrometer. The content of Au is about 87.1 %-89.4 %, the content of Ag is about 10 %, and the contents of Cu and Fe are little. Meanwhile, the authors have analyzed the production process of the hanging screens.The filament inlaid craft is the main production process. Finally, by re-carving and rejuvenation of more than 30 places of the loose and missing inserts in the hanging screens, the integrity of the cultural relics was restored. On the basis of scientific detection, an effective protection and restoration plan of the cultural relics was proposed, and then more in-depth research on the production process of the Qing Dynasty hanging screen was discussed. It provides some experience and reference for the protection and restoration of similar cultural relics in China.
