Peacock & Williams Class 50 amphorae (P&W AM 50)

Single sample

The type is frequently known as the ‘Chalk’ amphora.

General appearance

Our sample is a very hard brown-red (5YR 6/6) fabric with tan (7.5YR 7/4-6/4) surfaces, a rough feel and hackly fracture. Typically sherds may have a cream outer surface (Peacock & Williams 1986, 201).

Hand specimen

This fabric is composed of a slightly golden micaceous clay containing ill-sorted inclusions. Small quartz (0.1–0.2mm) is common, while larger inclusions comprise common quartz, and sparse feldspar (normally 0.1–1.0mm), red-brown and black rock fragments and limestone (both 0.5–3.0mm).

Thin section

A calcareous clay with sparse quartz silt, which contains common coarse to very coarse subangular sand-grade material, composed mainly of quartz, together with sparse grains of untwinned feldspar, chert, limestone and other rock fragments. Occasional subrounded grains of altered lava, and a single grain of pyroxene (c 1.0mm) are also present. Subangular grains of amphibole up to 0.3mm, plagioclase feldspar, biotite and zircon occur rarely.
