No full textThe preliminary work for the edition of the complete catalogs of Civic collections of Vicenza (Italy) was an occasion to study by energy dispersive x-ray fluorescence (EDXRF) about 30 small bronzes and plaquettes of Italian Renaissance. It was necessary to perform in situ analyses directly in the museum without any possibility of sampling or cleaning the objects. We report the results of quantitative analysis on principal and trace elements; moreover, patina problems and the possible clues for raw materials provenance are faced
A new methodology for comparing IR reflectographic systems
No full textIR camera systems can be used for reflectographic analyses to detect and visualize underdrawings in paintings. Five technologies have been compared: CCD Si, FPA InGaAs, FPA HgCdTe and InSb detectors, and a vidicon tube. The comparison has been performed studying the relative contrast measured on homogeneous pictorial layers in infrared regions between 800 and 5000nm. This comparison was completed through measurements of spectral transmittance (400-2500nm) made with a spectrometer. The results have been related to the kind of pigment and of medium and to the thickness of the layer. All the systems have been tested also on the field, on paintings belonging to different museums. Some results are discussed
