Application of Non-Destructive Techniques. The Madonna Del Latte Case Study

In the frame of a research project involving a private collection of artworks a panel painting representing the Nursing Madonna (Madonna del latte) was studied by means of scientific examination.The Department of Chemistry and Industrial Chemistry (DCCI) of the University of Genoa carried out non-invasive exams, combining imaging techniques with analytical analyses.Infrared reflectography (IRR), infrared false colour (IRFC), UV fluorescence (UVF), X-ray fluorescence (XRF) and reflectance spectroscopy in the visible range (vis-RS) were used to analyse the painting palette thus obtaining more information on a possible creation date of the painting.Some of the most interesting results are the identification of a freehand underdrawing and the usage of lead white, cinnabar, Fe-based pigments for yellows and browns and Cu-based pigments for blue and green colours.The scientific results, as well as historical researches allow the hypothesis that the Madonna del latte was authored in the early 16th century by a Florentine artist, probably a scholar of Baccio della Porta

A Characterisation Study on Modern Bronze Sculpture: The Artistic Patinas of Nado Canuti

Artistic patination is a traditional colouring technique for metal sculpture, employed by artists in ancient and modern times for aesthetic purposes. Today, knowledge of the artistic value and the chemistry of this superficial chromatic layer, called \u2018artistic patina\u2019, can be successfully acquired through a close collaboration between living artists, foundry artisans, and scientists. Starting from several interviews with the Italian artist Nado Canuti and foundry artisans, specific information was gathered about patination methods and the artist\u2019s attitude towards materials restoration. Afterwards, the patinas most used by Canuti were reproduced to study their nature before any ageing or degradation. Their chromatic values, morphologies, and compositions were studied employing a range of techniques such as colour measurements, scanning electron microscopy with energy dispersive X-ray spectroscopy, and micro-Raman spectroscopy. The collected data revealed the formation of main compounds (cuprite, cassiterite, rouaite, chalcocite, isocubanite, and ferroxyhite) and additional compounds (atacamite and CN-containing compound). The scientific results, as well as the artist\u2019s statements concerning the patinas\u2019 significance, maintenance, and conservation, will contribute towards the future care and preservation of Canuti\u2019s sculptures
