How can you identify real Delftware pottery?

Real Delftware pottery often carries factory marks, hand-painted details and signs of age on the glaze. Genuine Delft Blue from the Netherlands usually has markings on the base showing the factory name, artist initials or production number. Royal Delft pieces often include the De Porceleyne Fles bottle symbol and the word Delft. Experts examine the weight, brushwork and firing quality when checking authenticity as hand-painted Delft Blue usually shows tiny differences in the blue decoration, unlike printed copies with repeated patterns. Many collectors use auction records and museum examples for comparison, where some rare Delft Blue chargers from the late 1600s have sold for over €20,000 at European auctions.
