ciji u jami, kao i u oksidacionim uslovima, u električnojlaboratorijskoj peći, brzinom zagrevanja od oko 3 o C/mini zadrškom od 30 minuta, na maksimalnoj temperaturi od750 o C. Relativno velike razlike upijanja vode ovih uzorakavezane su kako za hemijski, mineraloški i granulometrijskisastav sirovine, tako i za uslove pripreme uzoraka,oblikovanja i pečenja.Veće vrednosti upijanja vode u oksidacijisu očekivane zbog činjenice da u redukcionim uslovimadolazi do taloženja sitnih čestica ugljenika u poramana površini uzoraka i na taj način smanjuju poroznostmaterijala, a time i upijanje vode.Viša vrednost upijanjavode za uzorke pečene u jami u redukcionim uslovimau odnosu na fragmente može biti posledica ili nižetemperature pečenja, kao i režima pečenja, a ne treba isključitimogućnost razlike u hemijskom, mineraloškom igranulometrijskom sastavu polaznih sirovina, što bi trebalonaknadno utvrditi porozimetrijom, određivanjemukupne zapremine i raspodele veličine pora.ZaključakPrva faza projekta još nije privedena kraju. Naime,očekuju se još komparativne petrografske analize, čimeće se završiti ova faza.Planirano je da se u drugoj fazi ponovo naprave testpločice,ovaj put sa dodatim primesama i da se, nakonpečenja, ponovo urade sve fizičko-hemijske analize.Pretpostavlja se da će se, na ovaj način, doći do najpribližnijerecepture mase od koje se pravila vinčanska keramika.Potom će se, u toku proleća i leta 2005. godine,organizovati radionice, čiji će cilj biti, izrada replika vinčanskihposuda na terenu, na osnovu približne recepture,korišćenjem tehnika za koje se, na osnovu arheološkihi etnoarheoloških istraživanja, smatra da su primenjivaneu neolitu. Ovako se otvara novo polje dugoročnih istraživanja,koja će biti tema narednih eksperimentalniharheoloških radionica na lokalitetu Vinča - Belo brdo. electrical laboratory kiln, with heating being increasedaround 3°C/min and keeping for 30 minutes on the maximaltemperature of 750°C. Relatively high differencesin absorption are concerned with chemical, mineralogicali granulometric structure of the raw material, but alsowith preparation, modeling and firing conditions.Higher absorption in oxidation was expected for the reasonof precipitating particles of carbon in the surfacepores in reduction conditions, which leads to lower porosityand, in that way, to lower absorption. Higher absorptionof water at reduction conditions, for the samplesfired in a pit, could be a consequence of low firingtemperature, or firing procedure, but one should not ignorethe possibility of differences in the chemical, mineralogicali granulometric structure of starting raw material,which should be determined latter on by porosimetry,through determination of total volume and distributionof pores size.ConclusionThe first phase of the project is still going on. Comparativepetrographic analyses are still to be carriedout, and they will end the Phase I.It is planned to produce new testing pieces in thePhase II, with additional ingredients, and to repeat allphysical-chemical analyses. This practice could lead tothe most similar possible recipe for production of Vinčaceramics. Later on, during spring and summer of 2005,workshops will be organized, with an aim of producingreplicas of Vinča vessels on the site, based on the mostsimilar recipe and by using techniques considered to beused in the Neolithic, according to archaeological andethno archaeological research. In this way, a new field oflong-term researches, becoming the subject of followingexperimental archaeological workshops at Vinča – BeloBrdo site, would be introduced.Rentgenogram uzoraka vinčanskih zdela, koji pokazujeprisustvo kvarca, muskovita i albitaX-ray graph of the samples of Vinča vessels, indicating apresence of quartz, muskovit and albit131
