The upper element, or pestle, of a two-part cosmetic ('woad') grinder of the late Iron Age to early Roman period. It is of sub-circular cross-section with a tangential ring at one end and a radiused underside at the other.

It is possible that part of the functional underside is missing, either due to wear or adaptation after being broken, as the usual form exhibits a more pronounced curve where it contacts the lower element, or mortar (see UKDFD 50613).

The recorder notes that the find was made on a Roman villa site.
