Question
โ† History

Which of these consequences affected Mughal pietra dura inlay when excessive moisture permeated porous sandstone?

A)Increased salt crystallization and surface fracturingโœ“
B)Reduced heat capacity of stone sections
C)Decreased structural load-bearing capacity
D)Accelerated oxidation rate in gemstones

๐Ÿ’ก Explanation

Erosion risk increases because capillary action draws moisture carrying dissolved salts into the sandstone matrix; this causes salt crystallization โ€“ a disruptive expansion mechanism โ€“ within the stone. Therefore, fracturing ensues, rather than altered gemstone properties or heat capacity alone.
