Colchester (Early) Colour-coated ware 1 (COL CC 1)

Single sample

General appearance

Our sample is buff (7.5YR 8/4) and soft, with a smooth fracture and a harsh feel. The internal surface is covered with a thin buff or brown-grey (7.5YR 4/3) slip, the external a red-brown (5YR 4/4) one, much of which has been abraded. Many of the forms produced in this fabric imitate the Lyon industry, with globular beakers (sometimes roughcast) and hemispherical cups typical.

Hand specimen

The sample is dominated by fairly well-sorted (<0.1mm) abundant quartz, which occasionally measures to 0.7mm, set in a sparsely micaceous matrix of both silver and gold mica. Both limestone and red iron-rich inclusions are sparse and average between 0.1–0.2mm, although limestone can measure up to 0.4mm. On our sherd abundant sand roughcasting measures 0.4–0.6mm.

Thin section

A micaceous clay containing common muscovite and some biotite is visible in thin section. Common fine quartz and limestone (<0.1mm) are the main constituents, with fewer opaques and flint in a similar size range. Rare ill-sorted larger inclusions measure to 0.5mm, or rarely 1.0mm, and comprise primarily quartz (including polycrystalline), but also limestone, feldspar, opaques, clay pellets and argillaceous siltstone.
