The increased long-term visual degradation risk of the Taj Mahal's pietra dura inlay rises fastest when which mechanism dominates?

💡 Explanation

Water solubility recrystallization dynamics drive decay because infiltrating water dissolves and redeposits minerals within the inlay, creating cracks and efflorescence. Therefore, visual degradation progresses due to material loss, rather than just thermal stress or binder breakdown.
