This paper deals with a multi-analytical and long-term in-situ monitoring campaign for evaluating the state of conservation of some outdoor contemporary bronze sculptures of the environmental Gori Collection, at the Fattoria di Celle, located in the municipality of Santomato, Pistoia, Italy. Digital 3D models of the Cavaliere and of one of the thirty-three figures of Katharsis have been made by means of photogrammetry in order to characterize the artworks. On the same sculptures, the chemical composition of the corrosion patinas has been determined by Raman spectroscopy. Moreover, the protective effectiveness of the corrosion products layer has been assessed by means of electrochemical impedance spectroscopy (EIS). The analytical data obtained in the monitoring campaign, still in progress, are discussed as a function of the exposure time and conditions to outdoor environment of the works of art.

Abstract
This paper deals with a multi-analytical and long-term in-situ monitoring campaign for evaluating the state of conservation of some outdoor contemporary bronze sculptures of the environmental Gori Collection, at the Fattoria di Celle, located in the municipality of Santomato, Pistoia, Italy. Digital 3D models of the Cavaliere and of one of the thirty-three figures of Katharsis have been made by means of photogrammetry in order to characterize the artworks. On the same sculptures, the chemical composition of the corrosion patinas has been determined by Raman spectroscopy. Moreover, the protective effectiveness of the corrosion products layer has been assessed by means of electrochemical impedance spectroscopy (EIS). The analytical data obtained in the monitoring campaign, still in progress, are discussed as a function of the exposure time and conditions to outdoor environment of the works of art.File | Dimensione | Formato | |
