← HistoryWhich risk increases within Mughal pietra dura when thermal cycling weakens the anchoring?
A)Adhesive viscosity rapidly increases there
B)Inlay stone exfoliation probability increases✓
C)Crystal lattice phonon coherence ceases
D)Substrate outgassing induces delamination faster
💡 Explanation
Inlay pieces become dislodged by differential expansion, because the thermal stress exceeds bonding limits and causes a gradual increase in the frequency of total separation via strain–induced fracture. Therefore exfoliation occurs, rather than immediate structural failure of supporting stone volumes.
