North Gaulish White ware 4 (NOG WH 4)

Nine samples

The category incorporates closely related fabrics believed to have been produced in northern France. A number of distinctive form types, Bushe-Fox 22–30, Hartley Group I(iii), Hartley Group II (Gillam 238), Gillam 255 and some Gillam 272 were produced in these fabrics, which equate to Exeter FC2–5 (Hartley 1991) and Usk 1–4 and 10–12 (Hartley 1993). Although flagons (Davies et al 1994, 62–8) were also produced in similar fabrics, only the mortaria are represented here.

General appearance

This fabric is particularly susceptible to soil conditions and in some parts of Britain (eg Scotland, the Pennines and central Wales) it is rare to see a sherd with its original surface intact, resulting in a soft, powdery appearance. Typically it is cream (10YR 8/2–8/4) coloured, sometimes with a distinct greenish tinge, less often orange-brown (5YR 7/6), pale brown (7.5YR 7/6) or dull pink (10R 7/6).

Hand specimen

Although the inclusions in this fabric are generally quite fine and never abundant, their overall sorting varies and is not particularly diagnostic. However, three principal constituents occur universally, and these are quartz, red and black iron-rich grains and limestone. Quartz is usually well sorted, common and fine (<0.2mm); some samples have a scatter of iron-rich inclusions in this size range, but while still common they are more typically ill sorted and coarser, measuring up to 0.6mm. Limestone is generally sparser than the previous two and slightly finer than the iron-rich grains (0.2–0.5mm). Other less frequently occurring inclusions are feldspar, red-brown rock fragments (possibly sandstone), and fine silver mica in some samples.

Trituration grits are tiny and common on Gillam 238 (Plate 55b), Hartley I(iii) and Bushe-Fox 22–30, but they can be very sparse on Gillam 255 and 272. Their main constituents are quartz and angular grains of white or grey flint or chert, occurring in varying proportions, and normally measuring 0.2–0.4mm. For Hartley Groups I(iii) and II it is usual for the trituration grits to extend over the upper surface of the flange, and both internal and external gritting is combined with fine horizontal scoring. Bushe-Fox 22–30 has the scoring and grit on the inside only.

Despite the wide variety in this fabric, they, like North Gaulish White ware 2 can be characterised by ill-defined iron-rich inclusions which bleed into the matrix, and this together with the trituration grits, general appearance and suite of forms make it a readily identifiable fabric. The fracture, general appearance and flint or chert trituration grits are similar to Colchester White ware, Wiggonholt White ware and others produced in Norfolk.

Thin section

The single sample sectioned for this group has an isotropic clay matrix containing common well-sorted angular and subangular quartz, normally measuring 0.1–0.3mm, and fewer ill-sorted limestone, sometimes appearing as streaks. Rare flint or chert is also visible in a similar size range, as are common opaque inclusions and iron staining (to 1.0mm, but usually <0.5mm). No mica is visible, nor are trituration grits present in this section.

Source

Although in the past a source in Pas-de-Calais has been suggested for these fabric variants, a north Gaulish one is now considered more appropriate. Production undoubtedly took place in many centres, including Noyon where kilns are known (Ben Redjeb 1992a; 1992b).
