Based on the concept of the earlier Clay series, the Plain Clay Series is made. In this rudimentary Clay series the fingerprints of the hands that squeezed the clay are still visible, making each piece of furniture a unique handmade product. For the restaurant of the Groninger Museum, the material has been developed further in order to make it more suitable for public use. The clay of the Plain Collection, is treated in such way, that the pieces don’t need to be lacquered like the original Clay series. Through a special technique, the material is pigmented in order to create the different colors of the collection: Black, Blue, Red and Natural. On request custom pieces can be made.
