The type is also known as Dressel 21–2.
Our sherd is pink-brown (2.5YR 6/6) with pink-cream (5YR 7/4) surfaces and a very thin cream-coloured (10YR 8/3) self slip on the outside. Smooth and hard, it has an irregular fracture.
This fabric comprises a fine, calcareous clay with common fine mica (to 0.3mm on the surfaces), primarily gold but some silver. Inclusions are ill sorted with calcareous ones abundant in aggregate, and consisting of limestone, shell and microfossils. Limestone is common, occurring in two size ranges: a groundmass of small (<0.2mm) grains and larger ones measuring to 0.9mm, while microfossils and shell are less common and occur between 0.2–1.5mm. Other inclusions are sparse, but include red-brown rock and iron-rich inclusions (0.3–0.5mm) and quartz (0.4–0.7mm).
A micaceous (mostly white), calcareous clay containing common subangular sand grains (up to 1.2mm) occurs. Included in this group are quartz, fine-grained calcite, schistose rock and feldspar. Some of the calcite is clearly derived from shell. Silt-grade material is common, while microfossils are sparse.
This sample is in a different fabric from that described by Peacock & Williams, although the petrology suggests that it could share the same general source area in Campania or Lazio (D Williams, pers comm).
