The Saint-Amand-en-Puisaye Clay Service is made from stoneware clay (grès) originating from the Morvan region in central France. The area's clay deposits are connected to the geological history of the Morvan, where the weathering of ancient rocks has contributed to the formation of clay-rich soils.
Saint-Amand-en-Puisaye has a long tradition of stoneware production, closely connected to the clay deposits of the surrounding region. For centuries, local potters have worked with these clays, making the village an important centre of French stoneware craftsmanship.
The clay develops a warm beige colour when fired. A subtle reddish edge appears just beneath the glazed surface, revealing another characteristic of the material and its response to the firing process.
