← HistoryWhich weathering outcome increases in Mughal pietra dura architecture when rising damp transports salts?
A)Accelerated tesserae exfoliation fracturing✓
B)Inlay shifts during base expansion
C)Reduced thermal cycling resistance
D)Organic binder photodegradation slows
💡 Explanation
Rising damp causes **salt crystallization** within porous stone and inlays; mineral crystal growth exerts pressure, because water causes defects & grain growth within the pores. This results in tesserae exfoliation and fracturing, therefore accelerates damage rather than other listed outcomes.
