A long-term corrosion investigation of bronze sculptures exposed outdoor

Safeguarding our cultural heritage for the future generations is possible only by applying tailored conservation strategies. The safeguard is a complex task and often requires measurements to be performed on the artefacts. This paper describes an interesting case regarding the metallic artefacts belonging to the Gori Art Collection at Fattoria Celle (Pistoia, Italy). This collection of modern art, developed inside a project of environmental art, is facing different corrosion phenomena due to its permanent exposure to outdoor environmental conditions. A non-invasive and in-situ multi-analytical approach was recently started in order to assess the conservation state of the metal artefacts and to assure their long-lasting preservation trough the development of a conservation project. In this paper, the preliminary results of the monitoring campaign carried on the bronze sculpture "Cavaliere" by Marino Marini will be presented and discussed.
