Archaeometric analysis of an organic substance from flint arrowheads from the Tumulus Culture Cemetery in Górzyca upon the Odra River
Abstract
The aim of this paper is to verify a hypothesis of the organic origin of adhesives that were preserved on the surface of two flint arrowheads discovered in grave 26 on the cemetery of the Tumulus Culture at Górzyca upon the Odra River. The main purpose of the archaeometric analysis was to identify archaeological specimens (including their differentiation from geogenic bitumic substances and food remains), as well as to recognise tar producing technologies of the Tumulus Culture communities. Preliminary archaeometric analysis showed that both specimens displayed features of organic anthropogenic materials, produced in the process of dry distillation of method with an additional vessel to collect the product. The hypothesis, was further verified in the course of microscopic analyses, which did not register any traces of raw material, e. g. birch bark. This, has suggested the use of an advanced production technology.
