← HistoryWhich consequence occurs in Mughal pietra dura when subject to prolonged temperature cycling?
A)Differential thermal expansion induces cracking✓
B)Material diffusion increases color saturation
C)Biogenic weathering consumes marble surface
D)Eutectic melting disrupts crystalline structure
💡 Explanation
Differential thermal expansion applies stress at the interfaces between the inlaid stones and the marble substrate because various materials expand at different rates. Therefore, cracking initiates and propagates, rather than changes in saturation or melting, under cyclic temperature changes.
