Investigation of the renewed diseases on murals at Mogao Grottoes

Abstract In the past few decades, a series of research, restoration and protection have been performed on the ancient murals in Mogao Grottoes. These treatments played significant roles in the conservation of the elegant art in Dunhuang. But whether the protection and reinforcement are still active and which materials are more appropriate remain unknown. These issues are crucial for the conservation of murals. On-site investigation on the murals in Mogao Grottoes has been carried out. The purpose of this investigation is to examine the renewed diseases of the murals which have been repaired before. It will also provide useful information about the function of conservation materials and their degradation mechanism.
