In this article we present an experimental approach focused on bipolar core technology. The main goal is to define the major constraints and parameters faced when identifying the bipolar component of the Early Pleistocene site of Vallparadís (Spain). For these experiments we have used the same varieties of raw materials and blanks as those documented in the archaeological record. The methodological framework applied in the study of the experimental sample is largely based on the most diagnostic parameters recurrently cited in bipolar-related literature: double striking platforms and opposite battering damage. This information has been encoded by grouping blanks, cores and detached elements in morphotechnical types. The results suggest that the reduction process is conditioned by the morphology and fracture consistency of the knapped nodules. Although blank morphology does not categorically determine the final shape of the cores and flakes, there is a clear correlation between them. The most diagnostic parameter for identifying bipolar objects in statistical terms is the presence of opposite battering damage. However, there are many non-diagnostic pieces generated throughout the bipolar knapping process. Hence we consider it pertinent to analyse the archaeological assemblage of Vallparadís according to alternative methodological approaches (e.g. morphotechnical types).
