摘要

The first point implies the execution of scientific examinations on some representative artworks, in order to characterize the pigments used and their contribution to the final colours, taking into consideration alteration phenomena, such as fading, darkening or repainting of the original artwork. A set of noninvasive analyses are currently being carried out by the CAV team to reach this goal, including spectroscopic, colorimetric and imaging examinations, performed using portable instruments. Spectroscopic exams, in particular, deal with X-ray fluorescence and reflectance spectrometry in the visible range, the first allowing recognition of chemical elements and thus materials, the second recognition of surface pigments and their behaviour under light, according to international standards.
