← HistoryWhich risk increases when constructing pietra dura inlay?
A)Thermal stress fracturing the stone✓
B)Oxidization reducing adhesive binding
C)Electrolytic corrosion loosening components
D)Differential settling damaging load paths
💡 Explanation
Thermal stress is more likely because differential expansion between the various materials in pietra dura during temperature fluctuations creates concentrated stresses that exceed fracture toughness; therefore, cracking appears, rather than electrolytic corrosion, which requires moisture present.
