What conservation challenges arise with polychrome stone sculptures?
Polychrome stone sculptures, renowned for their vibrant colors and intricate details, face significant conservation challenges. One major issue is pigment degradation, where exposure to light, humidity, and pollutants causes colors to fade or flake over time. Environmental factors like temperature fluctuations and air pollution further accelerate deterioration. Additionally, the layered composition of paint and stone complicates restoration, as traditional methods may harm delicate pigments. Conservationists must balance preserving original materials with stabilizing the artwork, often requiring advanced techniques and interdisciplinary collaboration. These challenges highlight the need for ongoing research and innovative solutions to protect these invaluable pieces of cultural heritage.
