โ† History

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

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

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