Another contribution to the TechnoHeritage2024 Congress was the poster, presented by our colleague and PhD student Laura Andrés-Herguedas, entitled “Er:YAG application to tempera paints: influence of pigment and binder nature”. The irradiation of the samples was carried out during her stay at the Dipartimento di Chimica e Chimica Industriale of the University of Pisa (Italy) with Alessia Andreotti and Alessio Ceccarini.
The interest of this study is to contribute and expand the knowledge about the effects of applying an Er:YAG laser (a conventional laser used in restoration) on pigments and tempera paintings. The evaluation and characterization of the tempera mock-ups were carried out between the scientific laboratories of the University of Pisa, and the University of Vigo.
These results are a starting point for the next step of the research, its use for the removal of artificially generated organic crusts.
