← HistoryWhat 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.
