A distinctive buff to pale brown (10YR 7/3, 7.5YR 6/4–6/6) clay with pale pink or brown-pink (10R 5/3, 10R 6/4–6/6) external wash and internal red-brown (10R 4/4–4/6, 10R 5/6) slip (thinner than that seen on CAM PR 1). Sherds are frequently soft with an irregular fracture and smooth surfaces where slipped, occasionally rough where unslipped. In some cases the slip may be burnished. Like other Pompeian Red ware fabrics, a limited repertoire of lids and dishes (here with small footrings) can be identified, but in this fabric the interiors of the dishes are distinctively rouletted.
This is a fine fabric with well-sorted inclusions of common quartz, usually <0.1mm, and variable amounts – normally sparse – of larger grains to 0.6mm. It is distinguished by common to abundant silver and gold mica, particularly on the surface (<1.0mm, usually <0.3mm). Other inclusions are sparse and fall within the same size range, but only red-brown or occasionally black iron-rich grains occur with any consistency. Other non-diagnostic inclusions are sparse limestone and white or red clay pellets. The underside of one of our dishes is gritted with quartz, measuring between c 0.5–1.0mm.
Abundant muscovite and less biotite mica are visible in a well-sorted clay matrix, comprised primarily of silt-grade quartz and rare feldspar. Rare inclusions of quartz (some polycrystalline) and feldspar measure between 0.1–0.4mm. Opaques are also visible, mostly silt sized, and sparse glauconitic pellets.
Lezoux has long been considered a potential source area on petrological grounds (Peacock 1977b, 154; Rigby 1989a, 120). The fabric is similar to Central Gaulish Terra Nigra and Central Gaulish Glazed ware 2 (Freestone 1989, 265).
