Delft Blue is the world-famous earthenware that has been produced in the city of Delft since the 17th century. Between 1600 and 1800, this earthenware was popular among rich families who would show off their Delft Blue collections to one another. Although the Delftware potters preferred to call their earthenware “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. In spite of this, Delft Blue achieved unrivalled popularity, and at its peak, there were 33 factories in Delft. Of all of these factories, the only one remaining today is Royal Delft.
