A mortarium kiln at Ellingham in South Norfolk was of late 2nd–early 3rd century date, and was slightly later than a similar kiln excavated at the site previously. Stamped mortaria, including sherds from vessels bearing a previously unknown stamp, were found within the kiln structure and in its fills.
Three pottery kilns excavated at Postwick near Norwich dated to the 2nd century AD. Each kiln was of a different structural type. Two were thought to have produced grey wares, while the third contained oxidised mortaria and white coarse wares.
Excavation at Two Mile Bottom, near Thetford, revealed the remains of at least three pottery kilns and other features of late Romano-British date. Again, the excavated kilns were all of different structural types. One kiln had apparently been built within the stoke hole of an earlier kiln, and its fills contained quantities of painted white ware of a type previously unknown in Norfolk. Pits, ditches and structural features dating to the Early Saxon period were also excavated, suggesting that activity continued from the Roman into the Saxon period.
