What are the effects of thermal stress on marble animal sculptures?
Thermal stress significantly impacts marble animal sculptures, causing both visible and structural damage over time. When exposed to temperature fluctuations, marble expands and contracts, leading to micro-cracks that weaken the material. Prolonged exposure to heat can cause discoloration, loss of detail, and even severe fractures. In outdoor settings, repeated cycles of heating and cooling accelerate erosion, particularly in delicate features like tails or wings. To preserve these artworks, protective measures such as shading, sealants, and controlled environments are essential. Understanding these effects helps conservators and collectors safeguard marble sculptures for future generations.
