Two samples
This group includes two mortarium samples. The clay is similar in texture to that described for Fulford’s (1975a, 26) Fabric 2b but our examples lack the red-painted decoration.
The fine groundmass of this clay, which is isotropic, enables the trituration grits to be easily identified, and this is therefore considered the best description of them in thin section. They range in size from c 0.3–0.2mm, although normally 1.0mm>, and are composed primarily of flint (some very brown due to iron staining), with fewer monocrystalline and polycrystalline quartz, quartzite and opaques.
