The term is used to denote decoration applied to the body of a clay vessel before it is glazed. The decoration may also be applied to a piece which has been covered with a layer of slip used to disguise the clay body and then the piece is glazed and fired. The decoration is most commonly painted, in which case the additional Technique term ‘painted’ should be entered. In most instances, objects with underglaze designs are then given a clear or less frequently, coloured, glaze. This is assumed so not generally specified in the Description, but always indicated by the additional Technique 'glazed'. However, if the overall glaze is not applied, the is is noted in the Description as 'unglazed'. N.B. The term ‘underglazed’ is not used in the records for the Department of Prehistory and Europe.
