This type is included here as an example of one of the many fabrics imported into Britain represented in the Peacock & Williams Class 10 (Dressel 2–4) amphora with bifid handles.
A very hard fabric, it is normally pale red (2.5YR 6/6) or brown (5YR 5/3) with lighter core (2.5YR 6/4). Although not represented amongst our samples, the external surface is frequently slipped cream (10YR 9/2). The fracture is irregular and large protruding inclusions result in rough surfaces.
The fabric is diverse in the hand specimen but is united by ill-sorted inclusions up to c 2.5mm, comprising common angular feldspar (0.1–0.3mm with some grains to 2.0mm), light-coloured (grey or pink) igneous rocks (normally c 0.5mm) and sparse accessory minerals (<0.5mm). The clay matrix is calcareous, with varying quantities of limestone (0.3–0.5mm) and silt-grade material set in a sparsely micaceous (gold and silver) clay.
This sample has an isotropic calcareous clay with ill-sorted angular to subangular fine to coarse-grade sand, consisting of elongate sanidine feldspar grains, quartz, microcrystalline calcite, volcanic rock fragments, greenish clinopyroxene and rare biotite.
On the basis of petrology, the fabric may originate in southern Italy (Davies et al 1994, 21, ‘KOAN-3786’).
