This type refers to one of several fabrics used for the Dressel 7–11 amphora.
Our sample is pale brown (10YR 7/4) with an intermittent pale orange (2.5YR 7/6–7/8) core. Buff (10YR 8/3) surfaces are abraded, resulting in a powdery, soft fabric, although elsewhere, too, the fabric in general is described as soft (Peacock & Williams 1986, 119). The fracture is irregular.
This is a fine fabric with well-sorted inclusions set in a matrix of sparse fine (silver, rare gold) mica and common silt-sized quartz. Larger quartz grains (some iron coated) are also common and measure c 0.2–0.4mm. Other inclusions comprise sparse red-brown or, less frequently, black iron-rich fragments (to 0.5mm although normally <0.1) and red clay pellets to c 3.0mm.
A very fine matrix with abundant mica (muscovite and biotite) and silt-sized quartz occurs. Larger (frequently to c 0.3mm) ill-sorted angular to rounded inclusions are sparse to common, consisiting primarily of monocrystalline and some polycrystalline quartz and feldspar, but also fine-grained sandstone, chert (frequently iron-stained) and quartz-feldspar aggregate. Some quartz-rich clay pellets to 0.6mm, and opaques of a similar size or smaller to silt grade, are also present.
The type was made in southern Spain, where kilns have been reported (Peacock & Williams 1986, 118). The fabric itself is undistinctive and does not enable the source to be more precisely located within the region.
