| Popis: | This article shows the first pigment identification of the Campana reliefs, Roman architectural earthenware plaques. The Campana reliefs polychromy were investigated by applying a multidisciplinary approach involving non-invasive and micro-destructive techniques to some fragments with traces of colour found on the north-eastern slopes of the Palatine Hill in Rome. X-ray fluorescence analysis and reflectance measurements provided preliminary identification of pigments, which was subsequently confirmed by X-ray diffraction and elemental mapping by scanning electron microscopy-energy dispersive spectrometry carried out on micro-samples and cross sections, respectively. Yellow ochre, red ochre, lead white, calcium-based white pigment, Egyptian blue and minium were identified. In addition, PIL (Photo Induced Luminescence) imaging was performed, identifying the macro-distribution of Egyptian blue, even on plaques without visible traces of colour. |
