| Metals Fine Silver: 99.9% pure silver Sterling Silver: an alloy of 92.5% fine silver, and 7.5% copper 24k Gold = 99.9% pure gold 22K Gold = 90% gold, 10% silver and/or copper 18K Gold = 75% gold, 25% silver, copper, and/or zinc Shakudo: an alloy of copper and gold (around 4%) Shibuichi: an alloy of copper and silver White gold, rose gold, green gold, or other colors of gold are composed of 24K gold and other metals, which change the color of the gold from yellow. Because enough enough copper, palladium, or nickel is needed to achieve a color change, these alloys are always 18K or lower. Mokume Gane: A laminate technique composed of fused sheets of varying alloys that are hammered, carved, and/or filed to expose a cross section, creating unique patterns. This technique is similar to damascene steel. I repoussé sheets of unpatterned, straight grain mokume and grind the surface afterwards to reveal the resulting cross section of metals. |
