What are the effects of acid rain on marble pots?
Acid rain significantly impacts marble pots by accelerating chemical weathering. Marble, composed primarily of calcium carbonate (CaCO₃), reacts with acidic rainwater containing sulfuric or nitric acid. This reaction dissolves the marble's surface, creating pits, cracks, and a rough texture. Over time, structural integrity weakens as details fade and edges become rounded. In severe cases, inscriptions or decorative carvings may disappear entirely. The damage is irreversible, making protective coatings or indoor placement crucial for preservation. Acid rain's effects are exacerbated in urban or industrial areas with higher pollution levels. Regular maintenance and pH-neutral cleaning can help mitigate further deterioration.
