Five samples
This is a pale orange-brown (nearest value 2.5YR 6/6–6/8, but estimated as slightly paler) fabric. Surface colour is brown (10R 5/6) or orange-brown (2.5YR 6/8, 2.5YR 4/8) with a distinct orange under-cast.The slip is of high quality, silky smooth and usually semi-lustrous. It is hard fired with a smooth fracture and feel.
The inclusions are well sorted and consistently <0.1mm. Abundant limestone dominates, with fine mica common (mostly silver but some gold) in the break and flakes up to 0.4mm typical on the surface of the vessels. Other sparse inclusions are red-brown and black iron-rich grains, quartz and red-brown ?rock fragments (the latter occasionally up to 0.7mm).
A silty clay with some larger inclusions of quartz, opaques (sometimes quartz rich) and particularly fragments of sparry calcite (some may be redeposited), frequently to 0.3mm. The sample contains abundant mica, with muscovite dominant, although some brown mica can be identified. A single siltstone is also present.
