Two forms of mortaria were produced in this fabric, both appearing to imitate samian forms. This copying is apparent in the non-functional spout of the Oxfordshire forms which clearly shows a lack of understanding of its purpose (Young 1977, 127). This mortarium type was widely distributed during the later 3rd and 4th centuries, particularly in the Severn Valley and Bristol Channel areas (Young 1977, 133-134).
