With the occasion of the exhibition Fatti come nuovi (20 October 1985–12 January 1986), where the most prominent artworks of the Poldi Pezzoli Museum in Milan were shown after restoration, a multidisciplinary project was launched between the Museum and the Italian Montedison group. This project aimed at evaluating several conservation products used at the time in ceramic and glass conservation, such as adhesives and retouching varnishes. In the frame of the project, two-component epoxy adhesives (Plastogen® EP, HXTAL NYL-1), acrylates (Paraloid® B-72, Plastogen® G), vinyl acetate dispersions (Vinavil®, Arkolyn), a polyester resin and cellulose nitrate adhesives (HMG, AGO® Goldsiegel) were studied in terms of their mechanical properties and colour change upon artificial ageing by UV-VIS radiation. Since then, the samples were kept in the dark. Almost 30 years later, the samples have been re-evaluated for changes in solubility and colour upon natural ageing. [ABSTRACT FROM AUTHOR]
