History

Which longevity bottleneck arises because iron sulfide inclusions form within Byzantine glass mosaic tesserae?

A)Cracks propagate from inclusion sites
B)Thermal expansion mismatches emerge
C)Alkali leaching accelerates drastically
D)Microbial surface etching intensifies

💡 Explanation

Crack propagation occurs because volumetric expansion from corrosion products exceeds the tensile strength; the spalling is caused by stress concentration at iron sulfide due to DIFFERENTIAL THERMAL expansion, and crack growth, therefore A, rather than bulk degradation.
