← HistoryWhich risk increases when the intricate pietra dura floral inlays in Mughal monuments experience thermal expansion?
A)Reduced compressive structural integrity
B)Accelerated material electrolysis reactions
C)Delamination because of shear stress✓
D)Elevated material ductile transformation
💡 Explanation
Delamination risk in pietra dura increases because differential thermal expansion between the inlay and matrix generates localized shear stress exceeding the adhesive bond strength, therefore inlays detach rather than adapt structurally via compression.
