The Westerwald Clay Service is made from stoneware clay originating from the Westerwald region in western Germany. The clay deposits are connected to the geological history of the Rhenish Slate Mountains (Rheinisches Schiefergebirge), where the weathering of ancient rocks over millions of years has contributed to the formation of rich clay deposits.
The Westerwald region has a centuries-old tradition of stoneware production, shaped by the abundance and quality of its local clay. As stoneware, the clay is fired at high temperatures, giving it a dense and compact structure.
Characterised by a low iron oxide content, the clay develops a soft, creamy colour when fired, reflecting the natural mineral composition of the soil.
