Which outcome results when excessive humidity permeates Byzantine glass tesserae?

💡 Explanation

Efflorescence results forming surface deposits due to increased Salt Migration (a form of diffusion) in highly alkaline glasses used in Byzantine mosaics. Therefore, crystalline salts appear, rather than brilliance, because water carries corrosive chemicals.
