Abstract
Portable energy-dispersive X ray fluorescence equipment, mainly composed of a small sized X ray tube and thermoelectrically cooled X ray detector, were employed to analyse paintings. The frescos of Giotto in the chapel of the Scrovegni in Padua were analysed, and oil paintings by De Chirico, of which 15 of certain attribution, and 11 supposedly painted by De Chirico. The pollution effects on the Giotto frescos were determined by analysing sulphur on the surface, and the thickness and composition of golden haloes were also measured. The 11 oil paintings by De Chirico are possibly fakes, on the basis of the different fingerprints of authentified and unauthentified paintings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
