The introduction and dispersal of ceramic technology in Northern Europe was influenced by two ceramic traditions. Hunter-gatherer pottery from the East and pottery from Neolithic cultures in the South are possible sources of origin for the earliest pre-agricultural ceramic tradition in Northern Europe. The precise dating of pottery is essential for determining the earliest pottery in a given region, for mapping dispersal routes, and for disentangling the origin of the Northern European pottery. However, radiocarbon dating of pottery can be heavily biased by the freshwater reservoir effect, when aquatic resources have been prepared or stored in the pots, or have been used as temper. This paper explores the impact the freshwater reservoir effect can have on radiocarbon dating of pottery. Methods for identifying the presence of aquatic products are presented, and the possibility of reservoir corrections is discussed.
