Differences in style and fabric helps pottery specialists to identify vessels which are not of local manufacture.
It was a family industry, continuing through generations.The same basic techniques were used and the same types of vessel were produced in different areas, but the pottery has a regional character.Inclusions in the pottery, to prevent shrinkage in the kiln, vary between geological regions.The single flue type was in use from the Late Saxon period to the 13th c., and was superseded by the double flue type.Multi-flue types were also used later, allowing greater capacity and needing peat or coal as fuel.Kilns are divided into single, double and multi-flue types. Several experimental kiln firings have been carried out.
These have provided us with information on what could and couldn't work, and are useful for interpreting the remains of structures in the ground.
Methods of stacking vessels in kilns are interpreted from excavated kilns which contain partial loads, but can also be reconstructed from kiln scars on glazed pottery and kiln bars, and from the direction of glaze drips on decorated vessels.
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 study of pottery is an important branch of archaeology.
Plain cooking vessels and decorated 'urns' were again common.
