This group, comprising a restricted range of forms, primarily mortaria, is described by Young (1977, 117–21).
Colours for this fabric are similar to those described for the red-slipped ware, but sherds are more likely to have orange surfaces. Examples recorded here are orange (2.5YR 6/8) to orange-brown (5YR 6/6–5/6) with a grey or grey-green (2.5YR 5/0, 5Y 6/1) core. Some samples have either orange as above or pink (10R 5/6) margins; their slip is cream coloured (7.5YR 8/2, 10YR 8/2). Like those with red slip, these sherds have a smooth fracture; however, the slip and surface seem to have a greater tendency towards abrasion and therefore a softer, powdery feel.
This is essentially the same base fabric as described for the group as a whole, but one sample from the kiln site has large (c 7.0mm) limestone eruptions on the surface.
