History

Which outcome most plausibly results from thermal expansion mismatch when sunlight heats Mughal architectural elements featuring pietra dura?

A)Delamination stresses the inlay's adhesive
B)Substrate cracking from compressive loading
C)Accelerated oxidation of metal supports
D)Salt efflorescence damages porous stone

💡 Explanation

Delamination is the most likely outcome because differential thermal expansion creates shear stresses at the interface, overcoming adhesive bonds rather than compressing the substrate. Therefore, inlay detaches, rather than the alternatives which require other mechanisms/conditions.
