Delftware or Delft pottery, also known as Delft Blue[1] (Dutch: Delfts blauw) or as delf,[2] is a general term now used for Dutch tin-glazed earthenware, a form of faience. Most of it is blue and white pottery, and the city of Delft in the Netherlands was the major centre of production, but the term covers wares with other colours, and made elsewhere.
