Apulian red figured pottery is part of the most recognizable and appreciated artworks of Italian cultural heritage. The initial objective of the research was checking the non-authenticity of some parts of two important Apulian red figured vases, stored in the National Archaeological Museum of Naples and subjected, through the ages, to several unrecorded restorations. The results obtained, in addition to achieve the set goal, revealed the non-authenticity of the whole upper part of one of the two vases, supplied further knowledge on nineteenth century restoration techniques, for these vases never adequately described, but mostly underlined how the answers to the archeological questions can only arise from a detailed characterization of the materials, succeeded by a scientific multi-technique strategy. Specifically, the complete chemical–physical characterization of the samples was accomplished by inductively coupled plasma mass spectrometry, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy, X-ray diffraction, Raman and Fourier transform infrared spectroscopies. © 2016, Springer-Verlag Berlin Heidelberg.

The investigation was aimed at defining the compositional and structural characteristics of a group of monochrome blue faiences recovered in Pompeii to assess provenance on the basis of their technological features. Different complementary analytical techniques were used: Scanning Electron Microscopy (SEM) to investigate the morphological aspects of the samples and in particular of the interfaces, micro-Raman Spectroscopy and XRPD to identify crystalline phases and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) to assess the elemental composition due to its sensitivity to a wide range of elements and the adequate lateral resolution. Statistical data treatment of the elemental concentrations of both the ceramic bodies and the glazes allowed us to classify the objects into compositional groups and to verify the previously established archaeological hypothesis suggesting an Egyptian provenance for faience of Pompeii. © 2011 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
