As far as studies in the localization of ceramic work-shops in Provence are concerned, the rediscovery of a text written by a schola rat the beginning of the twentieth centwy, mentioning a factory at Mimet in the Marseille hinterland, led us to undertake both research in libraries and museums, and fleldwork in the area, in order to pick up the trail of the work-shop. Its exact localization and the nature of ceramics produced have been identified. The geochemical data analysis corroborated the homogeneity of the entire production of vessels. The potters of grey coarse ware supplied the areas of Marseille and Aix-en-Provence at the end of the twelfth century and the beginning of the thirteenth century, before being rivalled by the craftsmen of the Ollières centre in the Varand Varand especially by the potters of Uzège.
