Gold Inlaid Kingfisher Brooch on Bronze Plaque

• Shakudo - Japanese shakudo is a traditional alloy that has been used in Japan for centuries. It is primarily composed of copper and gold, with the copper serving as the base metal and the gold adding a yellowish hue to the alloy. Shakudo is known for its beautiful dark blue-black or black colour, which is achieved through the addition of a small amount of a patina-inducing element like silver or arsenic.
  
  The word "shakudo" itself can be translated as "red copper" in Japanese, referring to the reddish-brown color of the pure copper base metal before it is patinated. The gold content in shakudo is usually around 4-10%, but this can vary depending on the specific purpose or desired appearance.
  
  Shakudo has been traditionally used in various forms of decorative arts and crafts in Japan. It is particularly associated with metalwork, including sword fittings (such as tsuba, menuki, and kashira), jewelry, and small ornamental objects. The alloy's dark color provides a striking contrast to other metals like silver or gold, making it ideal for intricate inlay work or as a background for other decorative elements.
• Bronze - An alloy of copper and tin, traditionally in the proportions of about 9 parts of copper to 1 part of tin.
  
  The discovery of bronze in Western Asia in the 4th century enabled people to create metal objects which were superior to those previoulsy possible because of its strength and hardness, and it has been used throughout the world for weapons, coins, tools, statuary and other decorative items.
  
  It is very fluid in a molten state, and its hardness, strength when set, and non-corrosive properties makes it most suitable for casting sculpture.
• Foliate - Decorated with leaves or leaf-like forms.
