In Mughal pietra dura inlay, which outcome arises when a support stone’s thermal expansion differs markedly from the inlaid gemstone?

💡 Explanation

Delamination occurs because differential thermal expansion induces significant stress between the gemstone and the inlay matrix. The cyclical temperature variations cause a wedging action called 'thermal stress fracture,' therefore detachment, rather than improved brilliance or structural integrity.
