The figure is a cross section of the stack rather than a decoration laid on top, so filing or polishing cannot remove it.

Place it clear of the strongest stripes and cut its lines finer than the grain.","layout":"The pattern is the subject, so keep the form plain. Let the grain follow the outline of the object and close the edge with one narrow band left blank.","material":"Stack sheets of metals that differ in colour, such as copper, silver and shakudo, and bond them into a single billet under heat and pressure. Gouge into the face to expose lower layers, roll the billet flat, then raise it into shape. Finish by polishing and colouring so the layers separate."},"avoid":"Thin the layers too far while chasing a particular figure and one cut goes straight through, breaking the pattern.","study":["why the Getty AAT places mokume-gane (300455807) under metallizing","the twenty one layers and the chisel cut grooves on Ian Ferguson's bowl in the V&A (O120544)","its origin as decoration for sword fittings, and the difference from present day workshop pieces"]}}
