Summary
Mortaria manufactured at Colchester (Essex/GB) during 1st and 2nd centuries AD; wide distribution in eastern and northern England and southern Scotland during mid-late 2nd century AD.
Fabric samples
Scale (when present) in cm.
Introduction
Mortaria were produced at Colchester from c. AD 50/55, but until the mid-2nd cent. the industry was relatively small scale. Some Colchester potters moved to the Verulamium region during the 1st cent. (see VRMO). From c. AD 140 production expanded, influenced by potters from the Rhineland who developed colour-coated and sigillata in the same workshops. Only the 2nd cent. Colchester mortaria are considered here.
Fabric and technology
Fine textured cream or creamy-yellow fabric with some fine quartz, flint and red-brown ironstone tempering; gritted with quartz and flint.
Forms
Mortaria; several varieties, including hooked flange, deep vertical flange and short stubby flange with a narrow bead (e.g. Colchester forms 497, 498, 501. Gillam 263, 265).
Stamps
Several named potters; also herringbone stamps, which are particularly characteristic of Colchester mortaria.

Principally Colchester, but similar fabrics also produced elsewhere in East Anglia and perhaps Kent. One Colchester potter Regalis, also had workshops at Ellingham (Norfolk) and two, Cunopectus and Acceptus, stamped both mortaria and sigillata at Colchester.
Distribution
South-east England (East Anglia and Kent), northern England and Scotland. Colchester was a major supplier to forts on the Antonine frontier (55% at Rough Castle; 45% at Inveresk).
