From Green to Brown: Characterization of the Fast Alteration of Modern Greenish Enamels in Glass Windows

ChemPlusChem, EarlyView.
Spots and stains appeared on the modern green enamel from different stained‐glass windows as a consequence of environmental alteration. The multianalytical characterization showed a 3‐step alteration mechanism divided into Pb2+ lixiviation from the enamel, formation of hydrocerussite (2PbCO3·Pb(OH)2), and transformation into scrutinyite (α‐PbO2) and ...
