Antique Stanley Theodolite in Mahogany Box

• 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.
• 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.
