Does Delftware always have a mark? If an object does not have a mark, this does not necessarily mean that it is not Delftware, as not all potteries used marks. Only around a third of Delftware has a mark.

Is Delft pottery or porcelain?

Although the Delftware potters preferred to call their pottery “porcelain”, it was only a cheaper version of the real Chinese porcelain. Delft Blue was not made from the typical porcelain clay, but from clay that was coated with a tin glaze after it was fired.
