What is shakudo metal?
Shakudō (赤銅) is a Japanese billon of gold and copper (typically 4–10% gold, 96–90% copper), one of the irogane class of colored metals, which can be treated to develop a black, or sometimes indigo, patina, resembling lacquer.
What metal is best for mokume?
Traditionally, copper and its alloys were the most important metals used in mokume. For jewelry applications, there is a greater emphasis on silver and gold alloys, but copper alloys are very important to knifemakers and metalsmiths who are working on a larger scale. Pure copper laminates and performs well in mokume.
How is shakudo made?
Shakudo is a Japanese alloy used in sheet metal inlay or wire inlay. The technique involves inlaying gold, silver, and copper into a darkened copper base. Usually, shakudo is composed of 75% copper and 4-25% gold and 5-20% antimony.
What is mokume gane made of?
Mokume gane (mow-koo-may gone-ay) is a laminated metal, made out of non-ferrous (no iron) metal. It is believed to have been first created about 300 years ago in Japan. At this time, Japanese sword making was the highest art form in the country, and mokume-gane was developed to decorate the hilt of the sword.
What is Shakudo used for?
Shakudo Uses The Shakudo alloy is often used to make fine jewelry and ornaments. Jewelry pieces like rings, bracelets, brooches, buttons, butterfly necklaces, earrings and pendants are made from this metal.
What is Hepatizon used for?
Hepatizon is a purple metal created by alloying. It is stronger then bronze but less strong then Damascus steel. This material is created by mixing Bronze and Gold dust to create Hepatizon dust and smelting the dust in a furnace to create Hepatizon bars. These bars can then be used to create armour and tools.
Why is mokume gane so expensive?
As we’ve discussed, Mokume is made of non-ferrous metals, which means that it doesn’t contain iron. It is commonly made using precious metals and as a result is often more expensive. Damascus steel, on the other hand, is made of iron based alloys.
What is the difference between mokume gane and Damascus?
Q: What is the difference between Mokume Gane, Damascus Steel? Damascus Steel refers to material that is made like this using iron alloys (i.e. steel and stainless steel). Mokume Gane refers to patterned metals that contain only non-ferrous metals, or alloys other than those containing iron.
What is shibuichi metal?
Shibuichi is a traditional Japanese copper / silver alloy. The name translates into English as “one quarter”. Shibuichi has a nominal composition of 75% copper and 25% silver but can range from 5% – 60% silver. At 75% copper / 25% silver it has a pale copper color.
What is Damascene jewelry?

What is the gold content of shakudo copper?
Shakudo is the Japanese term for a copper alloy with a low gold content of between 2 – 7% and other small additions. 3% was typical. The aim was to produce chemically tinted finishes such as shades of grey more by control of the alloy content than by varying the composition of the colouring solution.
What is the melting point of shibuichi and shakudo?
There are particular problems in reticulating both shakudo and shibuichi, but consistent results can be achieved once all the variables are known Additionally, these metals can be chemically or heat colored later on a completed piece. Shakudo 1: 95% copper. 4. 75% fine gold melting point approximately 1080°C
Where does the term shakudo come from in Japanese?
Shakudō is sometimes inaccurately used as a general term for damascened decorative metal inlays of Japanese origin. These were widely known in the West as Amita damascene, from the name of a 20th-century manufacturer of such items for export.
