The quarry and workshop of Barranco Cardones (Gran Canaria, Canary Islands): basalt quern production using stone tools

Abstract

Querns for grinding cereals were essential in the everyday life of the Pre-European population of the Island of Gran Canaria as their agriculture was based mainly on barley and wheat, cereals processed for the most part in the form of roasted flour. Rotary querns and other grinding stones, nonetheless, have rarely been the object of research in the Canary Islands and the study of their operational sequence of production has only recently been initiated.
