Which risk increases when tesserae thermal expansion differs drastically from mortar?

💡 Explanation

Delamination risk increases because differential THERMAL STRESS causes shear forces exceeding adhesive strength, therefore mosaic layers separate rather than remaining bonded, resulting in cracking, rather than simply optical changes.

• Which outcome accelerated the degradation of mud brick ziggurats due to capillary action?
• Which outcome resulted from limits on transporting trade emissaries in Goryeo?
• Which consequence resulted from rope bridge failure under Zhang Heng’s seismoscope?
• Which risk was MOST greatly reduced allowing elaborate Mughal pietra dura inlay due to developing which adhesive application within waterworks?
• What critical risk increased during Inca terrace construction?
• Water damage risks rise notably when subsurface Mughal garden runoff erodes the mortar beneath 'pietra dura' inlay panels, permitting what mechanism?
