Coarse shell-gritted hand-made cooking pots, probably made near the confluence of the rivers Trent and Humber from the mid 2nd century AD onwards. The fabric is hard and coarse with a smooth but unpolished surface, grey, black, or brown in color. The body of the clay contains small fragments of white shell. Sandy wheel-thrown imitations, Dales-type cooking pots, were made in Lincolnshire, the Humber Basin, and probably around York at the same time.
