The text shows the results of the petrographic analysis of stone artifacts from site Grabowiec. Out of set of 87 stones, 19 artifacts made of stones were selected and underwent a petrographic analysis. The main goal of the conducted research was to identify the type of rock raw material used for execution of tools. Petrographic analyses consisted in drawing up an assessment and macroscopic description of a rock material, from which artifacts were made. The macroscopic description was enlarged by a study using binocular magnifying glass, in order to precisely define: overall external features of rocks (colour, degree of vapidity, compactness), structure and texture and the type of rock-forming minerals. On the basis of the petrographic study, the type of the used raw material was determined.

Specialist analysis of ceramics helps to identify the raw material used for their production and to determine whether the material was chosen deliberately for its specific parameters. The present study of Neolithic vessels and of sampled raw materials has shown that Linear Pottery population tended to use plastic Miocene clay, but silty alluvial loam was equally popular. A comparison between the types of vessels and ceramic bodies has proven that thin-walled vessels were more often made of material with a high content of grains of silty fraction, while thick-walled vessels were usually shaped from heavy clay. This suggests that there were certain rules to be observed when preparing the paste, despite the local diversity of raw materials

Early Iron Age settlement of the Polish “Old Country region is a relatively well documented period from recent archaeological fieldworks. Functionally distinct sites, such as strongholds, ceremonial places and cemeteries have been found, covering the chronology between the sixth and the fifth century BC. The results of an archaeometric study undertaken with the aim of approaching the production technology and providing some insights into the probable local or non-local provenance of the main pottery types found in such sites are here reported. Selected pottery samples and modern raw clays from three coeval and functionally distinct sites (the stronghold of Starosiedle, the ceremonial place of Kozów, and the cemetery of Sękowice) were characterized by different techniques, such as thin-section petrography, X-ray diffraction (xrd), scanning electron microscopy (sem) and X-ray fluorescence (xrf) spectrometry. Resulting data indicated the sharing of a single technological tradition among the three sites with no particular specialization concerning the functionality of each site. This tradition is characterized by the general use of non-calcareous illitic clays, which showed a high presence of kaolinitic clay minerals in the case of Starosiedle pottery and a high content of chlorite clay minerals in the case of pottery from Kozów. All the pottery types were fired under predominantly reducing conditions at relatively low temperatures between 700 and 750 °C.
