Within Byzantine mosaic art, which degradation outcome arises from prolonged thermal cycling?

💡 Explanation

Differential thermal expansion and contraction occur because tesserae expand at different rates compared to the underlying mortar, leading to adhesive failure; therefore tesserae detach, rather than grout erosion or bulk substrate fracture since these relate to separate decay paths.
