This study explores the emergence and dispersal of grog-tempered pottery in south-eastern Europe, particularly southern Romania. During the second half of the sixth millennium bc, a dynamic zone emerged between the Danube and the Carpathians, facilitating the spread of innovations through multiple communication routes. Among these innovations, grog-tempered pottery began to appear around 5300/5000 bc and became prevalent during the fifth millennium. Despite being frequent, its origins, dispersal, and intensity remain poorly understood. This article aims to trace and explain the emergence and distribution of grog-tempered pottery in southern Romania. By integrating data from existing literature with new results from macroscopic and archaeometric analyses of twelve pottery assemblages from Middle Neolithic, Early, and Middle Chalcolithic sites, the author seeks to provide insights into the significance of the first grog-tempered pottery in a south-eastern European context.
