Fabric and technology
Fairly sandy fabric; black, perhaps with buff surfaces in earlier examples; some quartz grits and soft white inclusions, occasional larger flint fragments. Black slip visible on outer surface of closed forms, and all surfaces of open forms, giving slightly lustrous finish. Hand-formed.
Forms
Early forms (1st-2nd cent.) mirror those of South-East Dorset BB1, but some types (e.g. bead-rim bowls) more common in early SWBB1.
Chronology
No evidence for pre-conquest production, but present on pre-Flavian military sites. Dominant 2nd cent. BB1 fabric in Exeter during 2nd cent. AD. but no evidence of production after early-mid 3rd cent. when displaced by South-East Dorset BB1.
Source

Distribution
