X-ray elemental map of titanium and EDS spectrum of layer 1 in cross section S4 (likely overpainting whites). a X-ray elemental map of titanium collected from a portion of cross section S4, i.e. multi-layered white paint removed from the artwork’s exterior, on the proper right side, close to the base’s rear edge at bottom, highlighting the presence of this element—likely in the form of titanium white—in layer 1. b EDS spectrum of a portion of layer 1, confirming in this area the presence of relatively high amounts of titanium along with other elements
