The coating system of bowed string instruments is often composed of several organic (e.g. siccative oils, resins) and inorganic (e.g. pigments, fillers) materials, variously mixed and/or overlaid. In two recent scientific studies performed by the Arvedi Laboratory of Non-Invasive Diagnostics, six large fragments removed from musical instruments during past restorations and attributed to important violin makers have been considered for an innovative non-invasive insight into their stratigraphies through Synchrotron Radiation micro-Computed Tomography.
