Gilded Daguerreotype in Worked Leather Case

• Daguerreotype - The first photographic image was achieved in 1814 by Frenchman Joseph Niepce, with first photographic with the camera obscura, an optical device that projects an image onto a screen. However, the image required eight hours of light exposure and later faded.
  
  Joseph Niepce continued working on improving his invention Louis-Jacques-Mandé Daguerre, an artist. Niepce died in 1833, but Daguerre carried on, and at a meeting of the French Academy of Sciences in Paris on August 19, 1839 announced he had discovered a new method of photography, the daguerreotype which he named after himself. The daguerreotype process reduced the exposure time from 8 hours to 3 - 15 minutes.
  
  In major cities, professional photographers of the time, known as daguerreotypists, invited celebrities and political figures to their studios, hoping that by displaying a selection of portraits in their windows, the public would be encouraged to be photographed.
  
  However the popularity of the daguerreotype was short-lived, and its use declined in the late 1850s when the ambrotype, a faster and less expensive photographic process, became available. However the ambrotype still required the services of a professional photographer and it was not until the invention of Kodak's Box Brownie in 1900 that the public were able to shoot their own photographs.
  
  Due to the short time (20 years) that the daguerreotype was popular, and the fact that the image was produced directly onto the plate, meaning there were no negatives, original daguerreotypes are scarce. Most daguerreotypes are portraits, with landscapes and street scenes being less less common.
• 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.
