Abstract
Non-destructive techniques (NDT) have enhanced their usefulness in the field of cultural heritage protection and have become valuable tools for the investigation of composing materials, as well as for the detection of alteration and degradation of various structures. In the current study, non-destructive techniques, based on digital photography processing and analysis (digital photography-Vis/UVF, portable digital optical microscopy, colorimetry, infrared thermography), are used for the examination of three composite contemporary artworks created on photosensitized cement. This approach was applied to a series of composite works (photosensitized cement surfaces) in order to understand the craftmanship of the artist, document the materials used and assess the overall condition of the artworks. The techniques and methods applied can be used as a benchmark for the study of similarly complex artworks and for conservation and restoration planning. This comparative study has shown that, although the three artworks under examination are composed of alike materials (cement mortar, plaster, photosensitive emulsion), they exhibit distinct condition states, which can be attributed to variations in the artist technique and application, as well as to their exposure to different environmental conditions.
