A partition member having partition walls arranged in a lattice is disposed in the vicinity of an upper surface of a molten metal mass. The upper surface is divided by the partition walls into a multiplicity of segmental surfaces. A forming starter member is brought into contact with the partition member so that the molten material adheres to a starter surface of the forming starter member, and is then separated from the partition member. The molten metal is drawn from each of the segmental surfaces, and the drawn metal is solidified to form a piece which has a cross sectional shape corresponding to the shape of the starter surface. With the use of forming starter members having respective starter surfaces which are different in shape from each other, it is possible to form pieces having various cross sectional shapes which correspond to the shapes of the starter surfaces.
