Which consequence arises when humidity gradients stress layered 'pietra dura' inlays?

A)Glycolic acid crystallization accelerates erosion
B)Differential thermal expansion induces delamination
C)Biofilm formation corrodes binding plasters
D)Oxidative stress causes pigment discoloration

💡 Explanation

Differential thermal expansion of materials in 'pietra dura' causes shear stress; because each expands uniquely with temperature/humidity, the adhesive layer can fracture, therefore separation/delamination occurs, rather than chemical erosion which attacks uniformly.
