Abstract

A study on the painting materials (pigments and binders) of the famous painting “Madonna col Bambino e S. Giovannino” by Sandro Botticelli, located in the Museo Civico of Piacenza (Italy), was performed before a recent restoration. The painting materials were investigated by the analysis of five millimetric samples taken in damaged regions. The pigments were determined using the micro-Raman spectroscopy, with the 632.8nm line of a He–Ne laser. Despite the strong fluorescence background, the nature of the ground layer (gypsum and anhydrite) and of most pigments (i.e. goethite, lapis lazuli, white lead) was determined. Gas chromatography coupled with mass spectroscopy (GC/MS) was used to determine the organic binder media, and in particular proteinaceous and lipid materials. Egg and animal glue were found, while no siccative oils were detected.
