This paper presents the archaeometric and chemometric authentication of a Renaissance-style oil painting on linen canvas, with plaster and barium sulphate-based primer preparation and bone glue as binder. By optical microscopy (OM), stereomicroscopy (SOM), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) and attenuated total reflectance–Fourier transform infrared spectroscopy (ATR-FTIR), a series of archaeometric characteristics were identified: the grain size of the chemical components of the paint layers, the 3D porosity distribution of the pigments, the degree of penetration between the paint layers and the varnish and between the varnish and the oxidatively anchored dirt, and the typology of the craquelure (craquelure network arrangement and morphology). By correlating the results obtained, it was possible to estimate the period of the painting as 1660 ± 3 years. |
