Site No. 20 in Przemyśl, is an important research point of the early medieval city. During field works, two parts of a casting mould for the production of axes were found at the bottom of the settlement layer. No traces of copper were observed on the discovered form, but there were visible signs of burnout outside. This form is affiliated to the Mierzanowice culture. Petrographic tests have been performed using polarizing and scanning microscopes as well as microapaleontological examinations. They allow the researchers to identify the mould material as spongiolite (spiculite), most likely coming from the vicinity of Przemyśl, where the outcrops of this rock are located. With high probability, it can be stated that this material comes from the upper part of the Lgota beds covering the aforementioned lithostratigraphic units. The type of raw material used meets the conditions for using it as a casting mould. The obtained data allow for conclusion about the local production of this form.
