In this brief article we present initial results of chemical analyses of flint samples from six Polish sites and one Ukrainian site near the Polish border. The purpose is to examine the extent to which Polish flint resembles or differs chemically from Scandinavian flint. Flint from five of the seven analysed localities proved distinguishable from Scandinavian flint on the basis of chemical analysis. We found that flint types which look the same can have different chemical compositions and that flint types which look the same and have the same chemical characteristics can come from places as far distant from each other as southern Scandinavia and western Ukraine.
