Archaeometrical studies on some bronze buckles with portable (Handheld) XRF spectroscopy

Portable handheld X-Ray Fluorescence Spectroscopy (pXRF) is very effective and widely used technique for chemical analysis in field of archaeometry. The most advantageous feature of this technique is the possibility of analysing objects, artefacts on the spot without any sample-taking. In this study raw materials of 31 buckles from 7th century AD made of various kinds of bronze and silver alloys were analyzed to check similarities or differences between these objects via chemical analysis. Concentration ratios and distributions of alloying (Cu, Sn, Pb, Ag) and minor elements (Sb, Bi, Zn, Au) in material of bronze artifacts may have useful information suggesting important data about provenance and technology. Our recent study 27 bronze and 4 silver buckles were analyzed by pXRF and the results were used in statistical evaluation in order to get closer to provenance of raw materials and alloying technologies
