Figure 11: (a) SEM images of surface morphology for assessing a laser cleaning process of a dolomitic marble. Marble surfaces after laser cleaning at 1064 nm on the right part of the images and remains of graffiti covering surface on the left; (b) SEM images of surface morphology for assessing a laser cleaning process of a lead white painting. Lead white layer after laser cleaning at 1064 nm shows craters of different sizes with the formation of lead globule.
