WHAT IS THE CHOCOLATE FLINT ?

CHOCOLATE FLINT: A variety of high-quality flint from the Holy Cross Mountains in central Poland, used by prehistoric peoples from the Mesolithic to the Early Bronze Age. It occurs in round flat nodules and in slabs no more than 10 mm (4 inches) thick. Chocolate flint is very homogeneous and has excellent flaking qualities. It was usually mined from shallow pits about 2.4 m (8 feet) deep. Four chocolate flint mines have been investigated at Tomaszow, Wierzbica-Zele, Polany, and Polany-Kolonie.
