Chemical and Laser Cleaning of Corrosion Encrustations on Historical Stained Glass: A Comparative Study

The aim of this research work was to conduct a comparative study on the effectiveness of the application of chemical cleaning versus laser cleaning in the removal of surface congruent dissolution products from a potash-lime–silica historical stained-glass sample. EDTA was selected as the chemical cl...
