The fabric is frequently known as Portchester D ware (Fulford 1975).
The colour of the break is typically cream (10YR 8/2) or cream-yellow (7.5YR 8/6), sometimes with a blue-grey (7/0) or light orange (2.5YR 6/8) core. Surfaces are usually cream or buff (10YR 7/2). The fabric is hard with a hackly fracture and harsh feel and the surfaces appear wet slipped by hand. A restricted range of forms is typical, including hook-rim jars, frequently rilled, flanged bowls and dishes.
An exceptionally dense, clean clay matrix contains abundant well-sorted, rounded and subrounded quartz, frequently iron-rimmed to pink and mostly 0.3–0.8mm, although ranging to 1.6mm. Red and black iron-rich grains are sparse. On other samples, not included here, sparse silver mica is visible on the surface. The fabric is distinguished from Verulamium Region White ware not only by vessel form, but in fabric by being slightly denser, containing larger quartz inclusions – more frequently pink in colour, and in some cases being micaceous.
This is well-sorted fabric with clean clay matrix. It contains abundant rounded and subrounded quartz, sometimes polycrystalline, and normally measuring 0.15–0.5mm with occasional grains to c 1.0mm. Common opaques and rare clay pellets normally fall within the average size range for quartz. The clay also contains sparse muscovite and biotite mica, together with rare sandstone and quartzite.
Kilns producing this ware are known within the Alice Holt industry at Overwey (Clark 1949; Lyne & Jefferies 1979), but other important sources can be found at Fareham and in East Sussex (Lyne 1994). The different source areas are likely to account for the presence of mica in some samples.
