This fabric includes beakers, jars, bowls and dishes decorated with a red-brown slip, as well as mortaria in what is known as a ‘Raetian’ tradition (Hartley 1997). It is sometimes redder (10R 7/8) than other Wilderspool fabric variants, and may have a pale grey (6/0) core. The slip is red-brown (10R 5/8) or purple-brown (10R 5/6) and on the mortaria covers the bead, top of the flange and any internal concavity. Jars and bowls are usually decorated on the exterior with diagonal stripes, though some types of bowls have a complete coating of slip. Beakers normally have an external slip which ends in a straight line just inside the rim (Hartley, 1981, 472), while roughcasting on the beakers covers the exterior from shoulder to base and consists of clay particles, between 2.0–4.0mm.
Our sample corresponds to that described for the industry in general. Trituration grits are as for the White-slipped ware and here are common and well sorted, comprising red-grey, fine-grained rock fragments (2.0–4.0mm) and quartz (1.5–3.0mm). Although not included here, some examples of red-slipped mortaria are fine and virtually inclusionless (Hartley, pers comm).
