A lower millstone at Sithney Green Watermill, 1958. It is a French buhr stone, with the face almost worn down to the plaster of paris backing. The cutting of the stone is of modern pattern, the older pattern being of a harp design. Millstones come in pairs and the base or bedstone is stationary. Above the bedstone is the turning runner stone which actually does the grinding. The runner stone spins above the stationary bedstone creating the "scissoring" or grinding action of the stones. A runner stone is generally slightly concave, while the bedstone is slightly convex. The mill was still at work in 1930 and operated with two pairs of millstones. By 1960 it had become derelict.
