Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.
Milling Early history - quern stones. Milling is the process by which cereal grains are ground into flour. Traditionally, and in some parts of the world to this day, this would have been accomplished by grinding the grain between two stones, a lower, stationary stone called the quern stone and an upper, mobile stone called the handstone.
