There is considerable variation in both fabric and slip colour for this fabric. Our two samples range between red-brown (2.5YR 5/8) with redder (10R 5/8) surfaces, and orange-brown (2.5YR 6/8) with a surface of similar colour. The slip is good quality and slightly lustrous, although it can be patchy. Sherds are hard with smooth surfaces and a smooth fracture.
In this fabric inclusions are well sorted, measuring <0.2mm. Red-brown, grey and black iron-rich grains, fine silver mica and quartz are all common. Superficially the fabric is similar to samian produced at Colchester, but they can be distinguished from each other chemically (Storey et al 1989).
The sectioned sample has a slightly micaceous (mostly muscovite with rare brown mica) clay with common silt-sized quartz and occasional larger quartz, opaques and clay-rich opaques to c 0.1mm. Rare inclusions comprise siltstone and fine-grained sandstone, to 0.4mm.
