18th Century Silver Verge Pocket Watch by John Brimble

• 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.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Fusee - The fusee movement was used in clocks and pocket watches from the mid 17th century. The fusee is a cone shaped drum within the works that is linked to the barrel of the spring, usually by a length of chain.
  
  As the mainspring loses its tension over time, the cone shaped barrel compensates for this by increasing the tension, by pulling the mainspring tighter, thus ensuring the time remains constant.
  
  Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.
  
  The fusee continued to be used in marine chronometers until the 1970s.
• Acanthus - A stylized leaf motif, one of the primary decorative elements of classical Greek and Roman architecture, derived from the genus of flowering plants in the family Acanthaceae, native to tropical and subtropical regions of the Mediterranean area. It is a common element in classical Greek and Roman design, and is often seen in Corinthian and Composite order columns and used as a decorative element in English, European and Australian furniture, particularly on the curve of a leg, and as decoration for a corbel.
• Fleur-De-Lis - The fleur-de-lis is a stylized lily or iris flower with
  
  three petals that has been used as a decorative motif for thousands of years. It
  
  often appears in Christian iconography symbolising the Holy Trinity and as an
  
  emblem that reflects the purity of the Virgin Mary. In decorative art and antiques
  
  decoration, the fleur-de-lis is often used as a symbol of elegance, refinement,
  
  and good taste.
  
  
  
  
  The fleur-de-lis has a rich history and in ancient times, it
  
  was associated with royalty, purity, and the divine, and it was used as a
  
  symbol of the French monarchy for many centuries.
  
  
  
  
  It is a common design element in ceramics, silverware, jewellery,
  
  furniture, and other decorative objects, and it can be found in many different
  
  styles and forms.
