The clay sculptures of the Guanyin Temple in Xinjin, Sichuan, were made long time ago. However, inappropriate materials, such as cement and plaster, were later employed for maintenance and restoration. A few of the clay sculptures are broken, missed, and severely damaged. Their restored parts keep shrinking and expanding, which have caused severe problems of expansion, distortion and falling-off. Therefore, some sculptures have needed repair. Daqi (lacquer) is insoluble in water but dissolves in organic solvents such as alcohol, acetone, xylene, and gasoline. It hardly dissolves in any solvent and can remain stable after drying. This property makes it uniquely durable and wear-resistant. Dried Daqi (laquer) can endure high temperatures and has excellent electrical insulating properties. In 2007, Daqi was used in a project to conserve clay sculptures in the Guanyin Temple. The proportion of components to make Daqi brink powder putty is follows: 50g brick powder, 50g Daqi and 10g water. Daqi was used as glue agent while applying gold foil. The whole restoration progressed smoothly using Daqi according to traditional techniques.
