Andrew Rockhead's Scottish Square Piano, 1800

• 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.
• 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.
