Both men and women assisted in making bread, with men performing many of the tasks. Women generally were the millers. Figures of women milling grain have been found in the tombs of the later Old Kingdom (c.2575-2510 BC) to early Middle Kingdom (c.2030-1640 BC).
Milling itself was a tedious process and the cause of many injuries. Several handfuls were place on a stone quern with a gently curve surface for milling. The upper surface is not perfectly smooth, but is kept somewhat roughed. A stone shaped like rolling pin with a curve to match the curvature of the grinding surface was rolled back and forth, grinding the grain into flour, which was caught in a container at one end of the quern.
