Fabric and technology
The TR fabric classification (after Hawkes and Hull 1947) is based on fabric colour and texture, and the extent and colour of the slip.
Off-white or pink (2.5YR to 10R 8/8) fabric with slightly sandy texture, with occasional rounded red-grog inclusions; polished coral red slip (10R 7/10-5/12) on upper surfaces of cups and platters and outer surface of pedestal cups.
Pink or buff (10YR 7/4 to 10R 8/8) fabric, slight sandy texture, completely covered with orange or pink (2.5YR 7/12 to 10R 7/10) slip.
Orange (10YR 6/10) sandy textured fabric, with polished dark red (10R 7/10-5/12) slip on upper surfaces.
Similar to TR1(C), with self-coloured, polished surfaces.
A variable group of cream to dark red fine-textured fabrics with smooth fracture. Highly polished self-coloured surfaces. Some have dark grey, dark chocolate brown or a lighter smoky grey haze.
Forms
Plates, cups and beakers.
Chronology
Production commences by c. 20-10 BC. The proportion of terra rubra in the Gallo-Belgic assemblage drops through the Augustan-Tiberian period, being replaced by terra nigra, and the ware has disappeared by the early Flavian period. The different varieties may be dated thus:
15 BC-AD 25
15 BC-AD 15
AD 1-60
AD 1-65
Source
The principal source is the Vesle valley, near Rheims.
Distribution
North-east Gaul, between the Seine, Moselle and Rhine. In Britain, south and east of the Severn-Humber line, with concentrations in central southern England, and Herts/Essex region.
