The Polish Lowlands are poor in high\-quality natural flint resources, which creates an ideal opportunity for research on its distribution. In this paper we present a comparison between macro\- and micro\-analysis of flint. Twelve flint artifacts were macroscopically analyzed by Jolanta Małecka\-Kukawka and Jacek Lech and the results were compared with those determined by electron probe micro analysis \(EPMA\). The results of the comparisons have revealed that in some cases the ‘eye of the researcher’ is infallible, but in some other cases the use of petrographic methods is necessary for correct flint source identification"]
