← HistoryWhich outcome arises when prolonged freezing temperatures affect moisture trapped behind a pietra dura inlay within a Mughal-era sandstone facade?
A)Inlay detaches via ice wedging✓
B)Sandstone dissolves under cryohydrostatic stress
C)Binder oxidation accelerates mosaic weakening
D)Differential thermal expansion reverses adhesion
💡 Explanation
Ice wedging causes inlay detachment, because water expands as it freezes creating localized pressure. Therefore the veneer will loosen, rather than the overall structure dissolving or reversible thermal effects dominating, as these conditions need longer exposure times at milder levels.
