 represent the results of ongoing projects which are based on specific archaeometric analysis and was conducted by several of researchers with different kinds of science. So you can see these people on this first picture. And this research was conducted on pottery from cemetery in Wichina. As you know, the on-files are very well known from the enormous amount of pottery and we know that and you can read the assumption which were made for two sites, so Wichina and Domazwap, so a really huge amount of pottery. From Poland, from the southwestern part of Poland, we know something about 300 locations of on-file period. So the vast majority of these are cemeteries, so this is a small conclusion that pottery is the main source of knowledge for this period. And traditionally in traditional way pottery are developed, are elaborated in a very traditional way so they are used to determine the chronology and the culture, as you can see on this picture, the table of chronology and typology was made for the Białowice group. It was noticed that the pottery involves a similar repeatable set of vessels which, thanks to the shape, suggest contact with liquids. That's why the idea was born. Funeral pottery made only for funeral rite and no use on settlement. Additionally, set of typical domestic pottery as conical necked vessels and pots but in materialized version were also placed in the grave. Another factor confirming this assumption was grave good arrangement that indicates ritual actions connected to ritualized drinking symposium libation. So as we can see in the inner group and the manifestation of domestic space as we can see in this outer group. These features observed at this cemetery in Białowice group were also observed in Wichina Cemetery which is elaborated by our research team. The conception of symposal drinking set and feasting customs were taken from the Mediterranean world. In connection with the situation of access to materials from the settlement and from the nearby cemetery in Wichina, there was an opportunity to take a different look at ceramics. We posted a few questions about the pottery. First of all, our vessels produced and used in the settlement were used as funeral ones. The second one, our vessels were made specially for burials. And third, what was the pathway from the settlement to cemetery how it looks like, how it could look. So pottery derived from the famous settlement Wichina which was discussed today. But I would like to mention that these materials were published only from the excavation conducted in the period 2008 and 2011. And the funerary materials derived from the nearby cemetery have never been elaborated until the project in 2016 was started. And now we will focus on these pottery assemblages. So the Wichina fortified settlement the frequency forms of ceramic items on the settlement show the most frequent occurrence of pots on flora and bolts. So you can see those forms. Comparing to the cremation cemetery engraves the most frequently were bolts, miniaturals, vessels and then vases. So we can assume that the ceramic forms are very similar from a stylistically point of view but the differences are the frequency of particular forms. The next step was to choose samples, pottery samples to archerometric analysis. So as you can see on this picture the samples were very similar both to the cemetery and to the settlement. The samples from the cemetery was derived from the three phases of functioning this cemetery but the most frequently was the samples from graves dated to the Halstead Sea period. And the results from petrographic analysis, thin sections analysis from settlement established beside the types, the amount and size of inclusions but they also indicate some ways of surface treatment. Namely the added slip layers were recognized on the surface both so-called kitchen and table pottery. And I hope that you see in these thin sections pictures these added layers. Chemical analysis indicates two different source of raw materials which will be located in the closest neighboring to the settlement. So now the analysis which were conducted in our project, so cemetery. So petrographic results show the most common inclusions. That's where mineral grains also organic material and grog were also used but particularly in the pottery dated to the Halstead Sea. The latter inclusions did not occur in the settlement samples. So both petrographic analysis from settlement and cemetery show that a prehistoric pottery workshop was characterized by the lack of the required combination of recipes. Another set of analyzes namely using the scanning electron microscopy allows to observe the process of surface treatment. A common characteristics were very careful surface treatment sometimes leading to the surface polishing. In the scanning image of many samples one can observe parallel grooving typical for ceramic surface smoothed with a hard tool with a smooth surface such for example as a pebble. On this picture 3 you can see rarely protruding sharp edged rock fragments. The next picture, this 4 picture show outer surface of the same sample where the canvitas formed as a result of smoothing residual organic matter is visible as traces of blackening process during filing. We can see increased carbon content the presence of diagnostic peaks of sulfur and nitrogen in the small picture here below so in the EDS spectra. At the edge of the same sections are seen thick layers characterized by small amount of grains and orderly arrangement of clay minerals. So this picture show it very clearly the layers distinguished by the green color in the last 3 pictures. So this is compared to this inner ceramic mass, basis ceramic mass. The same surface finishing were established at the settlement samples so we have these very similar features. On the outer surface of the one weasel it can be observed the characteristic of two step application of the slip so at the symmetry we have two layers of slip. The confirmation of the hypothesis about the possibility of using local raw materials will be tests of ceramic samples and raw material using the thermal and x-ray diffraction analyzes. So this is in progress and we don't have all the results of these tests. But physical features aimed to determine the degree of water absorption total porosity and wateredness so the features that are mind the potential suitably of ceramics for storing liquid substances and the technological level of pottery. Four groups were distinguished with degree of range of values. First groups were the lowest porosity and water absorption so the pottery are the best containers so it indicates that pottery could be the best containers for the storage of liquids. The group third and fourth, so these groups have the worst physical parameters so the fluid permeability is very high. We could observe no big weasels and amphoras and drinking set in the third and fourth group. Miniature weasels and special forms occur in the third and fourth group. The most of the domestic weasels according to the results of these analyzes could be big weasels, big amphoras, both pots and almost this assemblage of pottery is the most typical pottery of Białowice group. Ceramics have been also exercised for potential of organic residue by using chromatography analyzes. By examining the components that have been absorbed into pottery it is possible to explore pottery function in the past. This examination reveals remains of cereals, vegetable materials, pine pitch and resin, paraffin wax and bitumen. Comparing these results to physical characteristics and these four groups, this is the group of physical characteristics revealed that cereals will exist in each of these four groups. The most interesting are samples which pine pitch and resin, paraffin wax and bitumen. This material indicates to sealing the surface of pottery, comparing the physical features, samples of drinking set, so bowls and cups, but also pots and weasels were placed in the two first groups. So it is. So represent the best conditions to domestic activity. Sensor, so this item. The item compared to model of the oven has also remains of pine resin, what could indicate some time of the combust or of fragment substances. At the last interesting samples is represent by this large conical necked vessel where both pine pitch and vegetable material were established. It should be added that this vessel was an urn in grey. So we could suppose that first these vessels were used as container to storage plant material and then reused as a grave's good. So to conclude and sum up this multidisciplinary research we could say that some of vessels could be reused as funerary pottery, the most large vases and amphoras. Some of pottery like this very small vessels, miniature vessels and as pointed jaglets and pots which seems to have replaced large storage and cooking vessels were produced only for symbolic use for one use like for the funerary rights. In functional interpreting the pottery we should not be suggested only by the shape. The same forms of vessels could be used in different ways. And we have hoped that this positive results of our investigations could bring comparing analysis of physical parameters of pottery and trace or organic materials. And this direction, this way of conducting research could shed a new light to the enormous amount of pottery which is found at the Orphard period. So thank you very much.
