Plumber’s Piece is the result of experimentation with leather and inspired by the shape of membranes (rubber balloons) from expansion tanks.The constructive value of leather combined with the flexible rubber membrane creates a new visual language. The shape of Plumber’s Piece originates from the proportions of the existing membrane. The ribs give the material structural value, so that the vase remains in balance and the original properties of both materials are accentuated.
