History

Within Mughal pietra dura inlay, which degradation accelerates upon seasonal temperature cycling?

A)Matrix crushing and void formation
B)Oxidative darkening of stone color
C)Solute deposition within stone pores
D)Selective dissolution of binding adhesive

💡 Explanation

Seasonal changes cause differential thermal expansion between inlay and matrix (coefficient of thermal expansion mismatch), creating pressure and causing stress concentration due to differential expansion, leading to matrix crushing and void formation, therefore this is correct rather than color changes or dissolution which depend primarily on chemical interaction, not mechanical stress.
