Swanpool White-slipped ware (SWN WS)

Single sample

General appearance

Our sample is orange-brown (2.5YR 6/8), sometimes with a grey or brown (7.5YR 6/4) core, while the surfaces are slipped cream (5Y 8/1). The fresh break reveals a hackly fracture in this hard fabric with rough feel. Reed-rim mortaria are particularly characteristic.

Hand specimen

This sample is similar to the fabric described for SWN CC, but is slightly coarser in texture with the quartz normally measuring c 0.2–0.4mm, but ranging between 0.1–0.5mm. The surface is especially micaceous, with large silver flakes (up to 0.3mm) notable on the inside. A fragment of slag, possibly a stray trituration grit, is also visible in the break. Trituration grits are abundant, ill-sorted grains of black slag, measuring 1.0–5.0mm. Hartley (pers comm) notes that it is difficult or impossible to distinguish many Swanpool, Cantley and Catterick area 3rd and 4th century mortaria by fabric or other obvious means
