okumé Gane translates from the Japanese as 'eye of the wood grain'
Pure metal and its alloys is being used to create mokumé gane objects. Jewellery is mainly crafted in combinations of gold, silver, palladium and copper.
Here some of the unusual metal combinations that are being used in mokumé gane:
Shakudo - The most widely used alloy in traditional manufacturing; it is generally accepted as 4% to 5% gold in copper
Shibuishi - meaning one fourth, the alloy consists of one part silver to three parts copper. There are several grades ranging from 50% silver down to 13.5%
Kuromido - It is composed of 1% arsenic in copper. The metal is slighter darker and harder than copper.
The quite labour intensive process begins by fusing together multiple layers of alternating metals.
The layers or billet is forged and rolled out, reducing the thickness until the individual layers become very thin. Further forging and carving exposes the layers which present a fine moiré or wood grain pattern.
