Wedgwood Gilded Black Basalt Candy Boxes (2)

• Basalt - Basalt is a hard, dense volcanic rock formed from the rapid cooling of basaltic lava, and makes up most of the earth's oceanic crust.
  
  However it is also the name given by Josiah Wedgwood in 1768 to a fine black unglazed porcelain which he called Wedgwood Black Basalt.
  
  Using this fine-grained stoneware he was able to produce copies of the newly excavated Etruscan pottery from Italy, with a lustrous and smooth, surface, and this new innovation proved to be a huge commercial success.
• 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.
