Within grand Byzantine mosaics displaying detailed facial features, which degradation process reduces specular reflection most?

💡 Explanation

Selective surface crystallization creates micro-facets which scatter ambient light rather than reflecting it specularly, because surface tension drives crystal growth. Therefore, specular reflection decreases unevenly, rather than changing due to complete detachment, crushing, or reduction reactions that uniformly affect appearance.
