Gilded Floral Wall Panel with Marbled Frame

• 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.
• Marbling - A descriptive term for a finish applied to plastic, ceramics, glass, plaster or wood to imitate the colours and characteristic markings of various marble types. For moulded items such as the first three above, the marbling is within the item.
  
  Interiors and furniture were marbled from from the early 17th century to the late Victorian period. The craft was practiced by skilled decorators using a combination of brushes and sponges. Some of the finishes achieved were so realistic as to make it difficult to distinguish the marbled surface from the marble surface.
  
  Marbling is also a term applied to a finish for paper as often seen in the front and endpapers of old books. The marbling is achieved by floating the colours on water and then transferring them to paper. However the marbling finish on paper, as with the marbling finish on plastics, with its multitude of colours has little resemblance to naturally occurring marble.
• Gesso - 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 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. In painting, gesso is also used to prime a canvas prior to applying paint.
