Physicochemical characterisation of pottery from the Vinča culture, Serbia, regarding the firing temperature and decoration techniques

Abstract

A study of decorated Neolithic pottery samples from excavation site Pločnik, Serbia, was performed using X-ray powder diffraction (XRPD), Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) spectroscopy. Investigated samples belong to the era of the Vinča culture which existed at the central Balkan region from mid VI until the first half of V millennium BCE. The mineralogical composition of pottery samples and comparison of investigated pottery with thermally treated local clay indicated firing temperature in the range from 600 to 800°C. Two different types of white pigments have been identified in white incrusted decorations: calcium carbonate and Bone White (composed of crushed bones). This is the first evidence of use of bones for decorations in Vinča culture pottery from excavation site Pločnik. In addition to this, it was revealed that the potters used the iron reduction technique for obtaining the black decorations. [Projekat Ministartsva nauke Republike Srbije, br. 177021 I br. 177012]
