Abstract
The effect of laser cleaning on historical sandstone samples investigated by means of surface techniques SEM and EDX reveals surface damages such as scaling off, cracking of the grains, and even melting of the crust. Also differences in the binder quantities contained in the upper layers are observed. The presence of compounds containing C, Al and F in the dark coverage is confirmed by the EDX data and indicates that the encrustation originates from environmental pollution.
