In the course of excavations at the Mesolithic site Ludowice 6 (central Poland), apart from typical for this region flint artifacts, was acquired a collection of 533 stone artifacts (as of 2011 ). Among them present were remains of an industry, in the number of483 objects, the primary feature of which was coring oriented at production of blades, flakes and - as a consequence - tools of forms similar to those typical for flint artifacts. Also the techniques applied were analogous to those used in treatment of this material. The industry was based on several types of quartz porphyry, fine-grained red granite and ferruginous quartz sandstone. The artifacts from these raw materials was discovered on in small concentrations. However, subject to treatment were also grey granite, grey quartz sandstone, quartzites, gneisses, quartz as well as mudstones and slates. The collection contained 30 specimens identified as morphological tools. The analysis of retouch visible on them and results of preliminary use-wear study confirm their anthropogenic origin and indicate tool usage
