History

Which consequence arises when insufficient binder curing occurs within Mughal Pietra Dura inlay?

A)Increased sensitivity to thermal expansion
B)Decreased reflection off crystal faces
C)Elevated risk of structural resonance
D)Reduced optical spectral transmission

💡 Explanation

When the binder does not fully cure, its polymer crosslinking is weak, resulting in a low glass transition temperature. The low Tg increases the mismatch in the Coefficient of Thermal Expansion (CTE) between the stone and the binder; therefore, expansion leads to cracking versus maintaining structural integrity with the inlay.
