Table 4: Compounds identified by means of Raman spectroscopy in the main hall samples. Figure 5: Raman spectra of the sampled inks in the main hall of the Punta Begöa Galleries, with T1 being the most external layer, and T12 the innermost layer. In summary, the composition of the sprays was not just organic, but a mixture of organic and inorganic compounds. In addition, there were some pigments, such as PY74 and PB15, that seemed to be the most common [15]. For restoration purposes, and considering the number of ink layers in the main hall, one or more products will most likely be needed to remove them.
