← HistoryWhich consequence weakens mosaics resisting environmental thermal shock?
A)Differential thermal volume expansion✓
B)Hygroscopic cement degradation.
C)Accelerated tesserae crystallization
D)Substrate adhesive elastic deformation.
💡 Explanation
Differential thermal volume expansion weakens mosaics exposed to temperature fluctuations because each material expands differently, introducing stresses at interfaces, therefore grout cracking rather than uniform expansion occurs because different properties exist.
