Blue de Four

Contemporary visual music in the classical 18th century line.

Limoges Veritable Bleu De Four Cobalt Blue Porcelain by Studio Olaf Stevens

The kiln technique called “blue” was first used in 1770. Known as “Bleu du ROY”, it recalls legendary Limoges expertise. The technique relies on adding a considerable amount of cobalt oxide to the transparent high temperature glaze.
The piece acquires a pure shiny transparent glaze after it has been immersed in a glaze bath before being fired at a high temperature (1400˚C). The result is a deep, hypnotic blue that oscillates between midnight blue, navy and indigo.
The 24-karat gold ornaments could then be deployed on this intense blue, either in monochrome with white, or on the full blue background, drawing their inspiration from antique motifs or from paintings of the 18th century, such as the gallant scenes of Fragonard, which were always very popular.
Today these decorations are executed in 24-karat fine gold, hand painted or in the case of complex hand drawings supported by silk-screen printing. The result you are experiencing with the piece you have acquired

This particular piece has been handmade in our much valued atelier in Limoges, France. Both shape and dessins are designed by Olaf Stevens.

The manual craftsmanship applies to all stages of the fabrication process, from modelling the shape and making the mould, to the high-quality porcelain slip-casting, the glazing, the 24 karat gold application and the final firing which has been done in a kiln only fit and used for blue de four pieces. To achieve such high quality and authenticity, we have extensively studied the 18th-century technique and have invested in material and equipment to bring this traditional technique back to live.
