History

Within Mughal pietra dura inlay, which risk increased after repeated freeze-thaw cycles?

A)Accelerated compressive stress resistance
B)Galvanic corrosion between materials
C)Delamination along material interfaces
D)Improved thermal shock resilience

💡 Explanation

Frequent freeze-thaw stress weakened the adhesive bonds in pietra dura because differential THERMAL EXPANSION induced shear stress. This caused delamination, therefore the layers separated, rather than improving stress resistance or thermal shock.
