Details of relevant entry in The Pottery Kilns of Roman Britain by Vivien Swan
No record in Swann, site excavated in 1996 by East Riding Archaeological Society following a watching brief by Hull Archaeology Partnership. It was as an emergency excavation during construction of a lorry park.
“An area of approx. 11m x 6m was cleaned revealing a clay kiln, associated stoking pits and a waste pottery dump. Similar to those at Hasholme, the kiln had two pedestal supports for the pot floor, but was constructed at a shallower depth so that the top had been sliced off by the machine [during site clearance by contractors].
A very large quantity of pottery was recovered, which appears to be of 4th century date. It includes loop-handled jars, flagons, wide mouth jars, flanged bowls, carinated cups and flat bottomed dishes. “
