These exquisite earthenware pieces are made from raw clay, and in this case white. The same formula of raw material being used dates to the 18th century. 

For certain objects, a process called calibration is performed. This is when a machine holds a plaster mold, and by rotating it, the craft maker's hands pushes the raw material into the object's final shape. 

Other objects are formed by a process called stamping, in which the craftsman takes rolled out clay, and gently presses it into a plaster mold, resulting in the clay taking its form. 

Once calibrated, molded, turned, and trimmed, the 'open-work' can be done. The craftsman pierces the clay with a scalpal to create fine openings that are inspired by the work of lace-makers. 

After an initial fire, the 'biscuit' piece is immersed into an enamel bath. Each piece is then inspected, smoothed, and re-touched, as necessary, to guarantee its exceptional quality of finish.

It is on the raw glaze that the artisan paints freehandedly or positions the stencil using a crystal paper template stamped with tiny 'poncif' holes.  Once correctly positioned, it is dusted with charcoal powder, and the outline appears in the raw enamel.

Lastly, the artist applies oxide-based colors with a brush, a technique like watercolor, and this is how the objects are transformed into their true works of art.

The final firing glazes the enamel and the decoration, a culmination of a long manufacturing process.
