How does marble’s solubility affect water features?
Marble, a metamorphic rock composed primarily of calcite or dolomite, is prized for its elegance in water features like fountains and pools. However, its solubility in water poses unique challenges. When exposed to water, marble slowly dissolves due to its calcium carbonate content, especially in acidic or soft water. This dissolution can lead to surface erosion, altering the aesthetic appeal and structural integrity of water features over time.
The rate of solubility depends on water chemistry. Hard water with high mineral content may slow dissolution, while acidic water accelerates it. Additionally, dissolved marble can increase water alkalinity, affecting aquatic plants and wildlife. To mitigate these effects, sealing marble surfaces or using alternative materials in high-water-flow areas is recommended. Understanding marble’s interaction with water ensures long-lasting, beautiful water features.
