Highly decorated tableware, including fine red and whitewares, were available during the Early Roman period.
Imported wares, such as fine red samian from Gaul, were popular, and wheelmade pottery was manufactured in Britain.
Clay pits were usually dug quite close to the kiln, on the peasant's croft or common.
Firing was a slow process to raise the temperature gradually to 1000°C. Few workshops have been excavated, but most consist of buildings and sheds which were probably used to store the raw materials and leather-hard pots, as well as a manufacturing area.
The same basic techniques were used and the same types of vessel were produced in different areas, but the pottery has a regional character.
The similarity between Iron Age and Saxon pottery, particularly in East Anglia, can cause problems where no other dating evidence is available.
There is a large amount of archaeological evidence for the pottery industry from the Middle Saxon period onwards, in the form of products and production sites.
