Cliffe Black-burnished ware 2 (CLI BB 2)

Five samples

A wide variety of wares was apparently produced in the area, but only BB2 is included here.

General appearance

The colour of the break ranges from mid grey (6/0) to black, very often with paler grey or sometimes red-brown (10R 5/8) margins. Surfaces are similarly medium grey to black, and are burnished to an even metallic lustre. The fabric is hard, the fracture irregular and the feel smooth. A range of black-burnished forms were made in the fabric.

Hand specimen

Inclusions are generally better sorted (usually 0.3–0.4mm) than for Colchester and Cooling BB2: quartz (0.1–0.5mm) is less dominant, being common rather than abundant and more rounded. Silver mica is also common, measuring up to 0.2mm; black iron-rich grains (0.1–0.2mm) and black clay pellets (0.4–07mm) are sparse.

Thin section

This fabric contains abundant well-sorted angular silt-sized quartz, with fewer and frequently rounded larger inclusions measuring c 0.3–0.5mm, occasionally to 1.0mm. Muscovite mica is commonly identified, with rare biotite present. Also visible, normally in the larger size range, are common flint and polycrystalline quartz; sparse quartzite and feldspar. As for Cooling BB2, glauconitic pellets are common in both the silt grade and larger size.

Source

Production of BB2 at Cliffe is confirmed by a large quantity of material in association with production debris, but no kilns are known (Monaghan 1987, 33).
