Portable non invasive analyses for Cultural Heritage
2014
The requirements that the scientific analyses for Cultural Heritage must have are: nondestructive and noninvasive, multielemental, sensitive, reliable and sufficiently rapid, able to carry out measurements in situ on objects of all types, and to deduce information practically on-line. Among the techniques that fulfill these requirements we find: multispectral imaging, portable EDXRF, Raman and UV-VIS-NIR spectrometry. In this paper we are going to show some cases in which it will appear clear the necessity of the correct order with which applying the non invasive techniques and what data of each of them it is necessary to understand in situ to obtain the maximum of the subsequent scientific…
X-ray Fluorescence Spectroscopy applied to the study of three sicilian painted artworks
2009
This paper reports on three X-Ray Fluorescence (XRF) studies of ancient Sicilian painted materials: a 13th century canvas from Cerami (Enna, Italy), the Muqarnas wood ceiling of the 12th century Palatine Chapel (Palermo, Italy) and a delicate early 20th century viola d’amore, the property of the Conservatorio di Musica “Vincenzo Bellini” in Palermo. Information about the pigments and preparation layer mixtures used as well as inferences regarding various past painting techniques emerged from the interpretation of spectra and data analyses.
