Which mechanism prematurely degrades 'pietra dura' inlay when exposed on Mughal monuments like the Taj Mahal?

💡 Explanation

Differential thermal expansion subjects the marble matrix and inlaid gemstones to varying expansion rates, therefore causing stresses at the bonding interface because adhesion fails within the 'pietra dura', rather than all materials expanding uniformly.
