← HistoryWhich structural weakness can occur when differential thermal expansion stresses traditional indian "pietra dura" inlay in sandstone?
A)Stone cracking along inlay edges✓
B)Fungal growth between layered segments
C)Chemical leaching due to binder
D)Deformation because of weight distribution
💡 Explanation
Stone cracking at the inlay edges results from differential expansion. Thermal expansion differences between the sandstone and inlaid materials generate shear stresses at their boundaries due to strain, rather than directly initiating fungal activity or overall deformation, and disregarding binder chemistry.
