Who are we ?
Royal Design Longchamp, is located in Longchamp, in Côte d’Or, the historic heart of France, on the site of the former Longchamp earthenware factory. Since 1832 Longchamp has been a village built around ceramics. At the height of its activity, the factory employed a large number of workers. With such a rich ceramic history, today it is appropriate to live up to quality manufacturing.
Our asset is the mastery of the entire manufacturing process of our earthenware, from the selection of soils (sand, clay and kaolin) to the manufacturing of the paste to the finished products. The plaster molds are designed in our workshop; the enamels and colors are carefully chosen from our French suppliers.
The Royal Design Longchamp company is 100% French!Artisanal manufacturing techniques make it possible to produce earthenware of exceptional finesse and quality. Our workshop being a real small production factory, we master all stages of manufacturing.
Molding
The shape of the part is created by us manually or digitally (3D printing). Once the model is made in the modeling workshop, it is molded in plaster in one or more parts depending on its complexity.
Le Moulage
La forme de la pièce est créée par nos soins manuellement ou numériquement (impression 3D). Une fois le modèle réalisé à l’atelier modelage celui-ci est moulé en plâtre en une ou plusieurs parties suivant sa complexité.
Shaping
Sand, clay and kaolin constitute the essential basis of earthenware paste. Our earthenware is worked and filtered for a long time to obtain a quality paste. Once the paste is obtained, the pieces are made by hand by pouring or molding depending on their shape. The plaster of the mold being porous, it draws water from the slip which generates a thickness called cake. Once the desired thickness (5/6 mm), the mold is turned over, emptying the excess slip still inside. The piece then firms up in the mold until it is firm enough to be unmolded. The refinishing allows
then trim the seams and give the piece a smooth appearance by rubbing it with a sponge. The piece is then fired at 1030°C for 24 hours after which we obtain a biscuit ready to be glazed and decorated.

The mesh
Essential for protecting the biscuit, the glazing, transparent or colored, gives the biscuit its shiny or satin finish which enhances the decor. Glazing is done manually by dipping or by spraying for solid colors. Once enameled, the piece undergoes a second firing between 980° and 1010°C depending on the enamel used.
The decoration
Decoration by chromolithography
The decoration is applied by hand like a decal on a white enameled piece. This onethen undergoes a third firing between 780°C and 980°C which allows the decoration to attach to the piece.
Decoration by partitioning
The enamel is applied with a brush or pear in the partitions which form the decor of the room.
All our parts bear our brand and are accompanied by a Certificate of Origin.
