Effects of Drifting Sand Particles on Deterioration of Mural Paintings on the East Wall of Cave 285 in Mogao Caves, Dunhuang

Research at the UNESCO World Heritage-listed Mogao Caves identifies wind-driven sand particles as a significant contributor to the deterioration of mural paintings, particularly on the east wall of Cave 285. The study highlights that collision and adhesion of drifting sand particles accelerate the degradation process, posing a threat to the preservation of these irreplaceable Buddhist artworks. Investigators employed a methodical approach to analyze the impact of sand particles on the paintings, focusing on their physical interactions with the surface. This finding underscores the need for targeted conservation strategies to mitigate environmental factors affecting the caves' integrity.
