← HistoryWhich outcome occurs on Mughal 'pietra dura' when seasonal humidity cycles cause soluble salts to precipitate?
A)Accelerated sandstone dissolution
B)Surface layer efflorescence✓
C)Increased structural rigidity
D)Reduced thermal expansion mismatch
💡 Explanation
Surface salt precipitates causes efflorescence on pietra dura because cyclical dissolution and recrystallization exerts pressure within the porous stone structure, therefore disintegration occurs layer by layer rather than improving the inherent structural integrity.
