Gallia Lugdunensis Oxidised ware (GLG OX)

Single sample

General appearance

Our example is pale pink-brown (5YR 7/4) with surfaces showing wiping marks. It is soft with a smooth fracture and a powdery feel. The vessel is distinguished from that produced in CNG OX, not only in rim form and lack of internal concentric scoring, but also by being a stamped type.

Hand specimen

This fabric has a sparsely micaceous matrix of fine mica, primarily gold and less silver. The groundmass contains common fine well-sorted quartz (<0.1mm), and common black and red iron-rich grains. Set in this matrix is a sparse scatter of much larger angular to rounded quartz grains measuring 1.0–1.5mm. Trituration grits are sparse and normally measure between 2.0–3.0mm, with occasional fragments between 1.5–4.0mm. Aggregate quartz and red and white rock fragments are all present. No grits are extant on the remainder of our sherd and therefore no photograph is available here.

Thin section

A variegated calcareous clay matrix, containing common subangular grains of quartz-rich silt is visible. Fine flakes of mica up to 0.1mm are quite common in some areas of the slide. A few grains of subangular to subrounded quartzose sand are present, and one of these is a rock fragment composed of feldspar, quartz and fine aggregates of white mica. These may be included as trituration grits.

Source

Distribution indicates a source in the Lyon/Vienne area, and the type is rare elsewhere.
