Chinese Stone Grinding Wheel

A pale round disc with two small holes, like a very flat owl.

This stone grinding wheel is from Shandong Province, China. Hand-turned stone tools like this usually consist of a flat or dished base and a rolling or revolving upper piece that crushes what lies between them. A flat disc with a smooth, chalky grey-pink surface and a band of short, chiseled lines around the rim. Two small round holes sit close together near the middle. The edge is slightly irregular, with a few small chips. It is 22 inches wide, 3 deep and 22 high.

Two holes, and no explanation offered.
