• 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.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Ebony - Ebony is a close grained timber, black in colour. It has a fine texture which can be polished to a high gloss, making it suitable for venereering, inlay and stringing and its use as solid timber is resticted to small decorative items and ornamental decoration, such as chess pieces and musical instrument parts. The term "ebonised" means "faux ebony", timber that has been darkened during the polishing process to resemble ebony.
• Fire Gilding - Fire gilding is a process used in metalworking in which an amalgam of mercury and gold is applied to an object and then exposed to heat to vaporize the mercury and leave the gold behind in a thin layer. Fire gilding also is applicable to plating silver, copper, and copper alloys.
• Mahogany - Mahogany is a dense, close grained red-coloured timber from the West Indies and Central America. It was first imported into Europe in the the early 18th century and its use continued through the 19th century. It was popular for furniture making because of its strength, the wide boards available, the distinctive grain on some boards, termed flame mahogany and the rich warm colour of the timber when it was polished.. The "flame" was produced where a limb grew out from the trunk of the tree, and this timber was usually sliced into veneers for feature panels on doors, backs and cornices.
  
  Some terms used to describe mahogany relate to the country from which it originally came, such as "Cuban" mahogany, "Honduras" mahogany etc. However unless the wood has been tested the names assigned are more a selling feature, rather than a true indication of the timber's origin.
• Lion Mask - The lion mask has been used for centuries in various forms of art and design, including furniture, silver, and ceramics, and is usually y depicted as a stylized representation of the face of a lion, often with an open mouth and protruding tongue. and is often used as a handle, knob, or other decorative element.
  
  In furniture design, lion masks were popular in the neoclassical and Empire styles of the late 18th and early 19th centuries. They were often used as decorative elements on the legs or arms of chairs, as well as on cabinet and drawer pulls. It was also used as a handle, knob, or other decorative element.
  
  In silverware design, lion masks were often applied to tea and coffee pots, as well as on candlesticks, snuff boxes, and other small silver items. The lion mask was often used in combination with other neoclassical motifs, such as laurel wreaths or acanthus leaves, to create a sense of grandeur and classical elegance.
  
  In ceramics, lion masks were often depicted in relief, and were sometimes used in combination with other decorative elements, such as garlands or swags.
