Abstract:In Poland three types of flint (chocolate, spotted and banded) were intensively mined from the Terminal Palaeolithic to the Early Bronze Age. Although heating of flint to improve its flaking properties was practised across the world from ∼110,000 years ago to the recent, particularly in southwestern Europe, heat treatment of flint in Poland is known from only two sites.
