Abstract:
The aim of this paper is to present the methods for analyzing pigments and ceramic of the Middle and Late Bronze Age encrusted pottery. Particle Induced X-Ray Emission (PIXE) measurements were carried out at the external beam setup of the 3 MV Tandetron accelerator at IFIN-HH, Măgurele-Bucharest, in order to determine the elemental composition of pigments (and fabric). A 2.7 MeV proton
beam was focused to approximately 2 x 2 mm^2, the current has been kept under 5 nA, for a data acquisition time of 300 s per spectrum. A 500 μm thick Amptek Si-PIN detector, positioned at 45° with respect to the beam direction was used to measure the characteristic X-rays. The quantitative data analysis was performed using GUPIX software. The pigment was then analyzed using a Bruker Vertex 70 FTIR spectrometer equipped with a RAM II Raman module (with N2 cooled detector and Nd:YAG laser excitation source of 1064 nm). The results of the two methods were strikingly similar and allow for deductions concerning transmission of local tradition in pottery manufacturing and possible interregional contacts.
