History

Which consequence occurred as temperatures cycled during construction of pietra dura inlay within Mughal-era structures?

A)Mortar strength became insufficient
B)Inlays fractured due to creep
C)Differential thermal expansion occurred
D)Oxalic acid stain proliferation occurred

💡 Explanation

Stones experience differing size changes that lead to cracking because differential thermal expansion occurred due to changes in temperature. Therefore, the contrasting expansion rates caused stress, damaging the pietra dura rather than mortar failure, creep, or oxalic acid proliferation.
