What outcome occurs regarding pietra dura when improper substrate preparation occurs during Islamic Mughal architectural construction?

A)Differing thermal coefficient delamination events
B)Consistent uniform crystalline lattice formation
C)Superior bonding through van der Waals
D)Increased compression minimal tensile failure

💡 Explanation

Differing thermal coefficients within installed components induce cyclical strain via differential thermal expansion; this causes eventual cracking via thermal fatigue rather than stronger bonding, because stress concentrating in the stone leads to eventual delamination.
