Which outcome accelerates deterioration when moisture penetrates pietra dura inlay?

A)Salt deposition beneath the stones
B)Oxidation of metal support strips
C)Weakening of lime-cement mortar
D)Fracture from thermal expansion mismatch

💡 Explanation

Salt deposition occurs because rising damp carries soluble salts into pores. These crystals form via capillary action and crystallize beneath the stones during cycles of moisture evaporation, exerting outward forces, therefore inlay detaches, rather than metal corrosion causing immediate visual damage.
