  [Ganoksin] Jewelry Making - Brief Notes on Shakudo
Shakudo is the Japanese term for a low gold content alloy which usually consists of between 2-7% gold and the rest copper.
Shakudo obtains a durable, purplish fl surface color when treated with a suitable solution.
This is used to best effect when the shakudo surface is combined with inlays (mechanical or fusion) which then results in high contrast pattern options.

 The Boone Collection - Image Gallery: Japanese Swords
Shakudo (literally “red copper”;) is a metal alloy that was invented and used exclusively by the Japanese.
There are fifteen grades of shakudo, all are primarily copper with an inclusion of at least four percent gold, and oftentimes small amounts of other metals.
When cast, shakudo is a dark copper color but it is most often treated with a boiling or “pickle” solution which results in a rich, velvety fl color with a violet sheen (Gunsaulus 1923:35-36, Rucker 1924:xxiii-xxiv).

I would like to plate shakudo (4%-6% gold in copper) onto a copper subtrate for subsequent patination.
Can a standard copper plating system and solution be used with a shakudo anode, or will the copper selectively plate out leaving the gold...

A variety of materials were used to create the yatate such as copper, brass, gold, silver, iron, shibuichi, sentoku, shakudo, ivory, bamboo, rattan, and chinaware.
Shakudo is a Japanese invention, and has no English equivalent term.
