AB The aim of this research work was to conduct a comparative study on the effectivenessof the application of chemical cleaning versus laser cleaning in the removal of surface congruentdissolution products from a potash-lime–silica historical stained-glass sample. EDTA was selectedas the chemical cleaning agent. Laser cleaning was performed using a 238 fs pulse UV (343 nm)laser. The comparative cleaning studies were carried out on a stained-glass piece supplied by theMaison Lorin Glass Restoration Workshop from Chartres, France. Given the complex nature, irregularthickness and heterogeneity of the encrustations found on the glass, the two cleaning approacheswere carefully performed step by step, while monitoring the process using an optical microscope.Raman spectroscopy and field emission scanning electron microscopy were used to characterize thechanges induced on the sample surface during the cleaning process. The results demonstrate that thetwo cleaning approaches were able to eliminate the outer surface dark layer associated with carboncompounds, as well as the external part of the white layer generated by the crystallization of salts,formed with the dissolved elements after a reaction with the air. A comparison of the advantages anddisadvantages of each method is also presented.
