Translating the functional aspect of ceramic covering material into emotional expressiveness – this is the fundamental idea of this product development. The starting point for the design of the surface is multi-colored shale. Grinding and removing of the stone structure obtain a graphic image of fine, mineral color gradations, which serves as motif for the ceramic application process. The ceramic surface created in this way is reminiscent of patinated stone floors, but also of flamed bronze. In the decoration element, the impression of oxidation and traces of wear is concentrated with copper and gold for ornamenting the design.
