Analytical investigations using Scanning Electron Microscopy (SEM), with Energy Dispersive Spectrometry (EDS), X-ray Diffraction (XRD), Infrared Spectroscopy (FT-IR) and High Resolution Magic Angle Spinning Nuclear Magnetic Resonance (CP-MAS NMR), were carried out on white, yellow and red overpaintings on Apulian redfigured pottery fragments (4th century BC) from Altamura, Monte Sannace and Canosa – among the most relevant archaeological sites in ancient Peucetia – in order to outline technological features and define the nature of pigments.

Abstract
Analytical investigations using Scanning Electron Microscopy (SEM), with Energy Dispersive Spectrometry (EDS), X-ray Diffraction (XRD), Infrared Spectroscopy (FT-IR) and High Resolution Magic Angle Spinning Nuclear Magnetic Resonance (CP-MAS NMR), were carried out on white, yellow and red overpaintings on Apulian redfigured pottery fragments (4th century BC) from Altamura, Monte Sannace and Canosa – among the most relevant archaeological sites in ancient Peucetia – in order to outline technological features and define the nature of pigments. The results obtained allowus to highlight that Apulian objects have an external appearancewhich is very similar to Attic objects, but that they are nevertheless different, as theyweremade using locally available raw materials employing similar but not identical production technology. Perhaps familiarity, rather than real and proper continuity with the Attic pottery tradition, would explain the analytical results. Moreover, this paper proves that solid state nuclear magnetic spectroscopy (CP-MAS NMR) is a useful analytical tool for the examination of ancient pottery, which is also suitable for the identification of its firing temperature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
