← HistoryWithin Mughal pietra dura inlay, which degradation risk increases from prolonged capillary action?
A)Salt efflorescence compromises the matrix✓
B)Thermal shock dislodges the stones
C)Oxidation darkens the stone facets
D)Abrasion polishes the surface layers
💡 Explanation
Salt efflorescence risks increase because capillary action draws subsurface salts to the surface. Crystalline growth exerts pressure, causing spalling and disintegration aka haloclasty, therefore damaging the intricate inlay rather than thermal cracking affecting larger stones.
