Which outcome occurs when excessive moisture permeates Byzantine glass mosaics?

💡 Explanation

Tesserae detach because freeze-thaw causes hydraulic wedging during repeated thermal cycling. This occurs because interstitial water expands upon freezing, imposing stress within pore spaces, therefore mechanically dislodging tesserae rather than solely chemical degradation effects under dry conditions.
