Mokumegane

Mokumegane (“wood-grain metal”) is a decorative metal laminate characterized by polychromatic wood-like grain patterns. The pattern is made by soldering together sheets of different metals to form a layered billet that is then hammer worked and cut to reveal the pattern. The metal may then be further worked to create objects with the unique patterning.
