History

In Agra's Mughal-era inlay, which degradation arises with fluctuating humidity?

A)Pietra dura detachment
B)Material chromatic shifting
C)Cement volume expansion
D)Gemstone abrasive weathering

💡 Explanation

Cycles inducing detachment arise because differential thermal expansion occurs from varying materials which stresses their glue interfaces – called differential thermal expansion – therefore adhesion weakens with expansion, rather than bulk chemical alterations or abrasion.
