I am often asked to make querns for demonstration purposes both in schools and in visitor centres like mills for example.
These examples have polished faces and edges. The rotary version has a rim on the bed stone to help view and collect the milled grain.
The ‘pebble ‘ grinding stone on the saddle has a ridge on the top to prevent the stone rolling over in the hand whilst grinding which can cause fingers to get squashed.
The quern in these images is used to mill Oland grain which is a variety cultivated 6000 years ago and still grown on the island of Oland in Sweden.
