CLAYER is a modular system made of high-fired porcelain, designed to foster a conscious and sustainable approach to food management. The project utilizes the specific thermal and hygroscopic properties of the material to create optimal conditions for storage, fermentation, cooling, and slow cooking. The multifunctional design consists of flexible, interchangeable modules: base pots in three sizes, matching lids, and a specialized cooling insert. While the porcelain provides a hygienic and moisture-regulating alternative to conventional kitchenware, the visual finish in birch green symbolizes freshness and preservation. The airbrushed color gradient accentuates the refined material surface, aesthetically embedding the values of sustainability into the modern daily routine.
