CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishCoatings in historical bowed string instruments made in Cremona (Italy) during 17th and 18th C. are often multi-layered systems, where organic binders are variously mixed with inorganic materials to enhance the sound and the aesthetic features of the objects. These materials were applied in superimposed coats in order to seal the wood porosity and prepare the surface to the application of the external varnish. In this work, we propose to employ photoluminescence (PL) micro-imaging, with hyperspectral resolution, and FTIR mapping to fully characterize the different layers of the multi-layered system, with a specific focus on the interface between the ground coat and the wood.
