Blended material by Tom van Soest Second life for old construction material. His blender grinds glass, bricks, concrete and even entire sinks into powder. By baking the powders in a specific mix at a high temperature, new stone-like materials are created with which you can build again: Blended Materials. Van Soest conducted many experiments to find the right mixture, shape and heating process. 'Trial bakes' show an enormous variety in color and texture.
