What are the effects of prolonged dryness on the structural integrity of marble?

Prolonged dryness significantly affects the structural integrity of marble, a natural stone widely used in architecture and art. Over time, lack of moisture causes marble to lose its natural flexibility, leading to micro-cracks and surface erosion. The primary effects include:

1. Cracking and Fractures: Dry conditions cause marble to contract, creating stress points that result in visible cracks.

2. Surface Erosion: Without humidity, marble becomes brittle, making it prone to flaking and powdering.

3. Loss of Luster: Prolonged dryness dulls marble’s polished surface, reducing its aesthetic appeal.

4. Long-Term Degradation: Repeated drying cycles weaken internal bonds, accelerating structural failure.

To mitigate these effects, experts recommend regular sealing and controlled humidity environments. Understanding these risks helps preserve marble’s beauty and durability in arid climates.
