“…Instead, in sample 16, the first area analyzed was the blue area, followed by the orange area in the upper area on the right. The blue zone is composed of azurite (Cu 3 (CO 3 ) 2 (OH) 2 ) [51]. The last points probably correspond to covelite (CuS) (Figure 15g) [52].…”

This work is focused on the characterization of metallic finds that are part of an ancient war biga from the Tomba della Biga, using different approaches for the diagnostics and also the conservation of this important cultural heritage. The materials analyzed were brought to light in the necropolis of Canal Bianco (Adria, Italy). The samples were analyzed using Optical Reflected Light Microscopy (ORLM), Scanning Electron Microscopy (SEM) and micro-Raman Spectroscopy (µ-RS). The results highlighted the occurrence of two different alloys (Fe and Cu-Sn-bronze) showing important structural and textural variations. These results, along with µ-RS, gave details on the surface and subsurface morphology, as well as the microstructures and the chemical and mineralogical composition of the finds. In particular, µ-RS highlighted the presence of magnetite and goethite as the main mineralogical phases for Fe-samples and malachite, azurite and Cu-oxide for bronze samples. In addition, an attempt was made to trace the manufacturing process, the purity of the alloys and the degree of slagging. Results of analytical studies show corrosion products of the samples which could be evidence of metallurgical aspects. The good state of conservation due to favorable conditions in the burial environment preserved the metal finds from intense corrosion, supporting the hypothesis that the samples reached equilibrium with soil during their life in the burial environment. This proposed methodology based on the microstructure, chemistry and mineral microanalysis allows the diagnostic and evaluation of the state of conservation of metallic finds.

“…In detail, in sample 13, the first area analyzed is characterized by a green patina, followed by a second area characterized by orange color and then the copper-colored area (Figure 15f). The spectra show that the first sampled point contains malachite (Cu 2 (CO 3 )(OH) 2 ) [51].…”

“…For example, Al Shenawa et al. 118 analyzed the effect of salt water corrosion in filled and unfilled ceramic filled polymer coatings before and after supercritical CO 2 exposure. As revealed in Figure 12 I, after exposure to CO 2 , the filled and unfilled systems had similar corrosion properties, while the filled coating had better wear resistance.…”
