← HistoryWhich outcome occurs when excessive moisture permeates Byzantine glass mosaics?
A)Tesserae detach via hydraulic wedging✓
B)Optical blurring impairs light refraction
C)Underlying iconographic dyes sublimate away
D)Gold leaf darkens due to oxidation
💡 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.
