“…In these specific areas, the Nd:YAG THUNDER COMPACT laser from Quanta System (Milano, Italy), operating at the second harmonic (wavelength 532 nm), was employed. Chemical cleaning was performed by a chelating gel at pH8 constituted by acetic acid (1 g), Carbopol ® Ultrez 21 (1 g), demineralized water (100 mL), and Triethylamine, namely TEA (4.1 mL) [32][33][34][35]. The cleaning intervention aimed to remove an altered repainted layer that had compromised the clarity of the original blue coloring of the Virgin's mantle.…”
