Archivio Gallone

The Archivio Gallone hosted at the Dipartimento di Fisica at the Politecnico di Milano, and comprises over 30 years’ work undertaken by dott.ssa Antonietta Gallone-Galassi.

This immense collection contains seminal work in the application of physiochemical methods for the analysis of samples from works of art, which has been carried out with the aim of providing information regarding artists’ materials and techniques. Thus, the archive is a testament to the condition and composition of works of art, and in some cases comprises significant examples of the evolution of working practices of a particular artist. On the basis of analyses carried out, it has been possible to address various art historical issues related to chronology and technique, and in some instances, even the attribution of a particular work to a specific artist. The intense scientific analysis of samples is accompanied by over 600 written reports, each of which presents the results and conclusions of analysis, along with images and, in many cases, significant graphs and tables.

Among the various analytical techniques employed for the characterisation of samples are optical microscopy (with observation at various wavelengths) and scanning electron microscopy (SEM) which have been combined with histochemical tests on samples, stratigraphic and point analysis of the elemental composition of areas within samples using X-ray fluorescence (SEM-EDS), X-ray diffraction, and microspectrofluorimetry.
