Fabric analysis was undertaken on: (1) a group of later twelfth century pottery from a kiln in Pound Lane, Canterbury, suspected of being used by a northern French potter, and (2) 'waster' pottery from a suspected twelfth century kiln of the same date at Tyler Hill, just outside the city, where the forms seem to be imitating those at Pound Lane. The results showed that the potters from both sites were utilizing the local London Clays. The similarities in texture in the pottery from both sites possibly points to shared technological recipes as well.
