Which risk became prevalent in pietra dura due to thermal expansion across seasons?

💡 Explanation

Inlay risks matrix failure because differential thermal expansion induces shear stress at material interfaces. Therefore cracking/decohesion within pietra dura is a primary risk, rather than dissolution or oxidation, which require chemical action.

• Which risk increased during medieval sieges when concentrated trebuchet fire weakened castle walls?
• Which increased risk resulted from undermining a medieval castle wall?
• Which outcome results when poor drainage management persists in a chinampa maize cultivation during the Late Postclassic Mesoamerican period?
• In historic Mughal water gardens, which limitation increased when seasonal silt blocked subterranean aqueducts supplying water for fountains and "pietra dura"?
• Which consequence arose in Byzantine mosaic art when tesserae experienced prolonged damp conditions behind basilica walls?
• Which consequence emerged when Alhazen studied light refraction?
