Analysis was performed having a Hanna Instrument HI 981037 Skin and Scalp pH Tester (Hanna Instruments, Woonsocket, RI, USA). 3. Outcomes and Discussion three.1. Painting Supplies Characterization Figure five shows the OM images with the two sections sampled in the wig (Figure 5a, sample A) and in the physique (Figure 5b,c sample B) of your sculpture. The primary painting layer scheme described in Figure 2 is visible. In specific, from the bottom to the prime of your wig sample a green-white-red-brown sequence is clearly distinguishable (Figures 5a and S1). Within this case the first white preparation layer isn’t recognizable because it was not incorporated within the sampling procedure. Etiocholanolone site Concerning the sample from the body (Figure 5b having a detail in Figure 5c) the initial white preparation layer might be seen in the bottom part of the stratigraphy. In this case the sequence is white-blue-white-green-brown. The brown layer appears to become thicker inside the body when compared with the wig. By signifies of VIL, SEM-EDX, FTIR, PyGC/MS and FT-IR each of the principal painting layers observed in OM images were identified. Micro-PIXE was made use of to acquire more data on minor and trace elements. FTIR and micro-PIXE spectral data at the same time as the Tenidap Autophagy SEM-EDX results (elemental evaluation) are provided as Supplementary Material.Coatings 2021, 11, x FOR PEER Assessment Coatings 2021, 11, 1335 Coatings 2021, 11, x FOR PEER REVIEW10 of 22 10 of 21 10 ofFigure five.

Blue and Green Pigments For what concerns the blue pigment, the preliminary evaluation by signifies of VIL was For what issues the blue pigment, the preliminary evaluation by suggests of VIL was preliminary analysis by implies of VIL was beneficial to recognize it as Egyptian blue. In Figure 6b a relevant image of VIL compared with valuable to recognize it as Egyptian blue. In Figure 6b a relevant image of VIL compared with determine it as Egyptian blue. In Figure 6b a relevant image of VIL compared valuable photograph is shown. The luminescence was observed only in the physique aspect with the sculpwith photograph is shown. The luminescence was observed only in element body component of photograph is shown. The luminescence was observed only within the body the in the sculpture and not in the head. VIL benefits were confirmed by signifies of SEM-EDX around the sample the sculpture and head.
