A ceramic rim sherd from a wheel-thrown Roman Oxfordshire white-ware mortarium dating to the period c. AD 240-410. It is 3.0mm thick at the rim, widening to 19.3mm at the flange before tapering to 9.9mm. It weighs 87.86g. The estimated exterior rim diameter of the vessel is 260mm

The fabric is an oxidised pinkish-orange, is hard, reasonably fine and tempered with fine mica and quartz sand (<0.5mm). The outer surface a has rounded white surface with occasional grey and brown, grit the interior white surface has larger pinkish quartzite grit (<3mm) below the flange.

The rim of the vessel, which has been partially chipped and is slightly in-turned with an arched, down-turned flange. It most closely resembles Young's Type M22.4 (1977, 76) which was in use between AD 240-410.

Above the flange a single, possible repair, hole (4.8mm diameter) has been pierced/drilled/punched through the entire sherd. Near to this, a second smaller hole (3.0mm diameter) has been partially pierced from the sherd's interior.

Note that a wider assemblage of pottery found from this site is fully described within Ripon (forthcoming)
