18th Century Mahogany Long-Case Clock by R Jackson

• 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.
• 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.
• Rosewood - A dense timber that varies in shade to very light brown to almost black. When rosewood is cut and sanded the colour of the timber will turn black, and after polishing and exposure to daylight, the surface will gradually lighten over time to light brown with black streaks.
  
  The name comes from the odour emanating from the timber when it is planed, sanded or cut.
  
  Rosewood was very popular for use in Victorian furniture in the second half of the 19th century, and at that time most of the rosewood was imported from Brazil. However it also grows in India and Indonesia.
  
  It is used in the sold for chairs and table legs, but for carcase furniture such as side cabinets and bookcases, and for table tops it is always used as a veneer.
• 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.
• Embossed / Repousse - Embossing, also known as repousse, is the technique of decorating metal with raised designs, by pressing or beating out the design from the reverse side of the object.It is the opposite of chasing, where the decoration is applied from the front. An embossed or repoussed object may have chasing applied to finish off the design.
• Satinwood - Satinwood is a dense pale gold coloured timber that was imported into Britain in the second half of the 18th century, and early 19th centuries from the East Indies and the West Indies. The name derives from the satin-like surface sheen when the timber is polished.
  
  It was used in the solid, as a veneer and in inlays. As well as furniture, satinwood was used for making musical instruments, barometers, boxes and clocks.
  
  It will usually be found on only the very best quality objects, presumably because of of its cost at the time.
