How does humidity affect the preservation of marble figurative sculptures?

Humidity plays a critical role in the preservation of marble figurative sculptures, often determining their longevity and structural integrity. High humidity levels can lead to moisture absorption, causing the marble to expand and contract, which may result in cracks, surface erosion, or discoloration over time. Additionally, damp environments encourage the growth of mold and biological stains, further degrading the artwork.

Conversely, extremely low humidity can also be harmful, as it may cause the marble to dry out and become brittle. To mitigate these effects, it’s essential to maintain stable humidity levels (ideally between 40-60%) in display or storage areas. Protective measures such as climate control, regular cleaning, and sealing the marble surface can help preserve these delicate sculptures for future generations. Understanding these factors ensures better care for marble artworks in varying environmental conditions.
