Composition of objects from nonferrous metals from Krasnoyarsky I burial ground

The results of X-ray fluorescence spectrometry analysis of objects from nonferrous metals from Krasnoyarsky I burial ground are presented. Krasnoyarsky I burial ground is dated from I to V century A.D. It is situated in Bardymsky district of the Perm Region, Russia.The analysis of the artifacts from 20 burials of the Krasnoyarsky I burial ground allow us to define the materials of things and to identify several complexes of items which demonstrate different combinations of metals. Analyses allowed to reveal recipes of alloys used in the manufacture of metal products by Krasnoyarsk population.The most common alloy is tin-lead bronze (CuSnPb) - 13 items. Also there are: tin bronze (CuSn, Cu>50%) - 8 items; tin alloy with copper (SnCu, Cu 96%) - 1 item.As a result of the investigation of items general tradition and specific elements in the burials items were noted. The composition of the Krasnoyarsk alloys are largely different from those used in the manufacture of items in the collections of Oshkinsky cemetery of the Vyatka River basin, Tarasovsky and Nyrgyndinsky I burial grounds of the Kama River basin.Most important, that in the investigated samples there are no things made of an alloy of copper and zinc (brass), which was widely used in the Middle Kama region for the production of different things. A significant group of samples is represented by tin-based alloys with the addition of copper, lead and arsenic.
