Japanese Mixed Metal Vases, Meiji Period

• Patination / Patina - In broad terms, patination refers to the exterior surface appearance of the timber, the effect of fading caused by exposure to sunlight and air over the course of a century or more, changing the piece to a soft, mellow colour.
  
  As patina is very difficult to replicate, it is one of the most important guides to determining the age of furniture.
  
  Patina is also the term applied to the bloom or film found on old bronzes due to oxidisation.
• Maple - Maple, native to North America, is a dense heavy timber from light to yellow-brown in colour. It has very little distincive graining unless it is one of the variants such as birds-eye maple or burr maple, so was not used extensively for furniture in 18th and 19th century, where cabinetmakers and designers preferred timbers with more distinctive features such as mahogany, walnut, rosewood and oak.
  
  Birds-eye maple has a seres of small spots linked by undulating lines in the grain, is highly sough and is used as a decorative veneer. Burr maple has larger and irregular grain swirls than birds-eye maple.
• 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.
