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'.
