Description
Summary:In this work, several non‐destructive testing and evaluation (NDT&E) techniques along with scanning electron microscopy with energy dispersive x‐ray spectroscopy (SEM‐EDS) were applied on Pentelic marble surfaces. The investigated Pentelic marble surface disclosed a representative decay pattern that usually develops in polluted urban atmosphere such as the Athens centre. The applied techniques aimed to collate as much as possible evidence about the physico‐chemical and aesthetical characteristics of the examined surfaces before and after the pilot cleaning treatments, in an attempt to configure an effective assessment methodology of cleaning interventions. The applied NDT&E techniques were fibre‐optic microscopy, colourimetry and laser profilometry. The results were encouraging enough to propose the use of these NDT&E techniques along with SEM‐EDS as an everyday assessment tool of cleaning conservation interventions on Pentelic marble.
