Salt MillDESIGN: Muller van Severen. the salt mill appears to be a sculpture rather than a functional tool. With these pepper and salt mills Muller Van Severen once again shows that everyday tools dont have to be purely functional nor seemingly invisible. The design duo reinterpreted the classic mill by reshaping the two basic parts of it the head and the cylender into two perfectly geometrical forms: a sphere and a cube. MATERIALS: Stainless steel.
