Additional file 1: Figure S1. Points analysed on the Kiss by the different techniques. Figure S2. Points analysed on the Garden airplane trap by the different techniques. Figure S3. Points analysed on the Entire city by the different techniques. Figure S4. Points analysed on the Zoomorphic couple by the different techniques. Figure S5. Points analysed on the Attirement of the bride by the different techniques. Figure S6. Points analysed on the Antipope by the different techniques. Figure S7.Chroma DI (1050-650, 650-550, 550-450 nm) of the Entire city: the red arrow points at the moon circle, not visible in the RGB image (yellow square). Figure S8. Spectral features of Prussian blue recognized in The Kiss: (a) in-situ Raman spectrum and (b) ER-FTIR spectrum, the absorption at 512 cm-1 is to refer to ν(ZnO). Figure S9. ER-FTIR spectra of three yellow tones in The Kiss which show the presence of silicates. Figure S10. In-situ Raman analysis of the Kiss identifying chrome yellow orange. Figure S11. In-situ Raman analysis of the Zoomorphic couple identifying iron oxide (green peaks) and lead white (blue peak). Figure S12. ER-FTIR reflection spectra showing the presence of alteration products in AP (green lines), KI (black line) ZC (red for the spectrum collected in dark tones, cyan for the one collected on light tones), VS (magenta line), GA (blue line) and EC (orange line). Zinc oxalate (magenta dashed line) was identified by the typical inverted doublet at ≈1364 and ≈1320 cm-1, attributable to the νs(CO) and by the derivative ν(OH) at ≈3400 cm-1 [1]. Instead, Zn metal soaps, probably zinc stearate (dark cyan dashed line), were rec-ognized by the sharp inverted bands at ≈1540 and ≈1395 cm-1 which can be reasonably attributed to the asymmetric and symmetric stretching of the carboxylate group in zinc stearate [2, 3, 4, 5]. |
