The Mold & The Casting
The liquid clay is poured into the specially made plaster molds, which have the shape of the piece to be cast.
Since 1653, Royal Delft has been synonymous with the craftsmanship of Delft Blue. Waterworks, the American design house renowned for its high-end bathroom fittings and accessories, selected Royal Delft as its partner to bring this centuries-old tradition into a new context.
Inspired by historic Delftware motifs and the elegance of the Edwardian era, the collection brings together Dutch ceramic heritage and timeless design. Through extensive research and innovative techniques, the distinctive blue-and-white decorations have been reimagined for exclusive bathroom fittings and accessories.
Each pattern is hand-painted by Royal Delft’s master painters, using techniques refined over centuries. Every piece is unique, bearing the individual signature of its maker.
Waterworks x Royal Delft is a meeting of tradition and innovation, bringing the art of Delft Blue into the contemporary interior.

Inside De Porceleyne Fles
Same building. Same recipe. Same gesture of the brush, passed painter to painter since 1653.
The liquid clay is poured into the specially made plaster molds, which have the shape of the piece to be cast.
Once all the water is absorbed in the mold, the mold can be opened, releasing the object. Casting seams are manually touched up and sponged until smooth.
The clay receives a special layer of diluted clay called 'engobe'. The product is then placed in the oven for the first time and fired to a temperature of 1100°C. After 24 hours, the product, now called 'biscuit', is removed from the oven.
The pottery painters hand-paint the traditional Royal Delft decorations on the vase. They do this with special brushes and a black cobalt oxide-based paint. The painter can achieve endless shades of color by using more or less water in the paint.
The decorated piece is now sprayed with glaze. The glaze gives the painting a white opaque layer. The vase then goes into the oven for 24 hours. During the second firing at 1200°C, the glaze melts into a transparent layer and the color of the decorations changes from black to blue. The chemical and physical reactions between sherd, engobe, paint and glaze determine the typical Delft Blue color.
