Use of Different Spectroscopic Techniques in the Analysis of Roman Age Wall Paintings

Abstract
In this paper the analysis of samples of Roman age wall paintings coming from: Pordenone, Vicenza and Verona is carried out by using three different techniques: energy dispersive x‐rays spectroscopy (EDS), x‐rays fluorescence (XRF) and proton induced x‐rays emission (PIXE). The features of the three spectroscopic techniques in the analysis of samples of archaeological interest are discussed. The studied pigments were: cinnabar, yellow ochre, green earth, Egyptian blue and carbon black
