Which consequence results from thermal shock on a Byzantine mosaic?

💡 Explanation

Tesserae spallation and detachment occurs because differential thermal expansion introduces stress exceeding the material strength, leading to fracture and loss of adhesion; therefore, spallation happens, rather than sublimation, which would require vaporizing the material.
