Royal Gouda Blue Delft Plate

Delftware is one of the types of tin-glazed pottery or faience in which a white glaze is applied, usually decorated with metal oxides, in particular the cobalt oxide that gives the usual blue, and can withstand high firing temperatures, allowing it to be applied under the glaze. Delftware forms part of the worldwide family of blue and white pottery, using variations of the plant-based decoration first developed in 14th-century Chinese porcelain, and in great demand in Europe.
