• Gilding - Gilding is a method of ornamentation whereby a thin sheet of gold metal is applied to items made of wood, leather, ceramics, glass and silver for decorative purposes.
  
  For furniture including mirrors, the sheet of gold is usually applied over a coating of gesso. Gesso is a mixture of plaster of Paris and gypsum mixed with water and then applied to the carved wooden frames of mirrors and picture frames as a base for applying the gold leaf. After numerous coats of gesso have been applied, allowed to dry and then sanded a coat of "bole", a usually red coloured mixture of clay and glue is brushed on and allowed to dry, after which the gold leaf is applied. Over time parts of the gilding will rub off so the base colour can be seen. In water gilding, this was generally a blue colour, while in oil gilding, the under layer was often yellow. In Victorian times, gilders frequently used red as a pigment beneath the gold leaf.
  
  Metal was often gilded by a process known as fire gilding. Gold mixed with mercury was applied and heated, causing the mercury to evaporate, the long-term effect of which was to kill or disable the craftsman or woman from mercury poisoning. The pursuit of beauty has claimed many victims, not the least of which were the artists who made those pieces so highly sought after today.
• Edo Period, Japan - The Edo period in Japan lasted from 1603 to 1868. During this time, Japan was ruled by the Tokugawa shogunate, a military government led by the Tokugawa family. The Edo period is characterized by a period of relative peace, stability, and economic growth, as well as by the development of a distinctive culture and society.
  
  During the Edo period, the capital of Japan was moved from Kyoto to Edo (modern-day Tokyo), and the country became increasingly isolated from the rest of the world. The shogunate implemented strict policies to maintain control, including the restriction of foreign trade and travel. However, despite this isolation, the Edo period saw significant cultural and artistic development, including the emergence of the ukiyo-e woodblock print tradition, the growth of Kabuki theater, and the flourishing of a vibrant merchant culture.
  
  The Edo period ended with the Meiji Restoration of 1868, which saw the collapse of the shogunate and the restoration of imperial rule.

• 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.
