The paper refers to the analytical characterization of Roman painted plasters dating back to the second century AD. The following techniques were used: optical microscopy (OM), scanning electron microscopy (SEM-EDS), micro-Raman and Fourier transform infrared spectroscopies (mu-Raman and FT-IR), X-ray diffraction (XRPD), colorimetry and thermal analyses (TG/DTA). The investigation analysed the chemical composition and structure of the plasters, the chemical composition of the pigment layers, the use of binders and any chemical alteration of pigments as well as deterioration of the samples. Stratigraphic analysis of plasters allowed identification of their individual components, which proved helpful in finding out more about the mural painting technique employed.
