Although Webster (1993, 232) describes the typical fabric as mid or silver-grey, our examples are dark grey (4/0–3/0) or grey-brown (7.5YR 5/2). These same sherds are hard with an irregular or hackly fracture and a harsh/powdery feel, but Webster (ibid) describes some surfaces as being lightly smoothed or burnished. The range of forms is restricted, frequently imitating Severn Valley and black-burnished style. However, narrow-neck jars with handles and wide-mouth jars are typical, as is wavy-line decoration, possibly created with a brush (ibid).
The inclusions are slightly ill sorted, composed primarily of abundant quartz, mostly c 0.1mm but ranging to 0.5mm. Other inclusions are sparse and comprise black and red-brown iron-rich grains (0.3–0.7mm) and fine silver mica.
Under the petrological microscope inclusions appear well sorted, containing abundant and frequently rounded monocrystalline and polycrystalline quartz (0.1–0.4mm) set in a micaceous (muscovite and less biotite) groundmass with sparse silt-sized quartz. In addition, sparse fine-grained sandstone, quartzite and feldspar can be identified. Matrix-coloured clay pellets, probably resulting from poor mixing of clay, can be common in the larger size range, while opaques are rare and normally measure <0.1mm.
Two kilns producing South Wales Reduced wares are known, at Llanedeyrn and Caldicot, but it is apparent that others existed (Webster 1993, 232–3)
