The Makó-Kosihy-Čaka Culture occupied a large territory of the Carpathian Basin at the turn of the Eneolithic and the Bronze Age. For several decades through rescue excavations in Slovakia, its source base has significantly grown. It is now more than 70 registered sites. Rescue excavation in Iža was carried out by the Institute of Archaeology of SAS in Nitra in the summer 2008. On this polycultural site ten features of the Makó-Kosihy-Čaka Culture were found and further potsherds of this culture were scattered in four other medieval features. The largest number of diverse material, over 85 % of total number came from the filling of the pit 31. Pottery and osteological remains of domestic animals were numerous, but small clay and stone artefacts were represented only at a minimum. The paper deals with the ceramic and decoration of the pottery artefacts. The pottery fragments were represented by ten types of vessels and their variants. Pots and pot shapes dominated in the local pottery production. The relatively numerous were also bowls, less jugs and cups. The shape assemblage was supplemented with amphorae, decorative pottery, glasses, plates and bottles. The main focus on the pottery deserves decorative ornamented pottery, which is represented by footed bowls and also in the Kosihy-Makó-Čaka Culture environment a unique vessel with rounded body, decorated with carved ornaments and girth lines made by technique called (Late Eneolithic) Furchenstich (stab-and-drag), in combination with a plastic crescent application on the shoulders. Based on the analysis of the material in this paper conclusions on the relative chronology and genesis of the studied culture are formulated in Slovakia, whereby we do not exclude the influence of the Kostolac decoration on the domestic population in Iža.
