Baetican (Green) amphorae 3 (BAT AM 3)

Single sample

General appearance

This fabric is typically green-cream (2.5Y 7/2) with cream (2.5Y 8/3) surfaces. It is hard with a hackly fracture and harsh surfaces. It appears to be associated only with the Peacock & Williams Class 31 form (Dressel 28).

Hand specimen

The sample comprises a slightly silty clay containing common well-sorted inclusions of feldspar, quartz (some polycrystalline), and mixed red-brown and dark rock fragments, normally ranging 0.3–0.5mm but occasionally to 1.0mm. Limestone, primarily decomposed and appearing pale orange in colour, occurs in a similar size and quantity. Sparse accessory minerals are also present.

Thin section

In thin section this sample has an isotropic calcareous clay containing well-sorted subangular medium to coarse-grade sand, comprising mainly quartz in approximately equal proportions of monocrystalline and polycrystalline grains. Also present are quartzose rock fragments, with feldspar, schistose and calcareous rock fragments, chert, green pyroxene and rare amphibole. Rare mica occurs but is not considered significant.
