French Giltwood Overmantle Mirror, 19th Century

• 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.
• Giltwood - Giltwood is used to describe a gold finish on furniture and other decorative wooden items, whereby a thin sheet of gold metal, called gold leaf, is applied to the surface for decorative purposes.
  
  Unlike gilding, where the gold leaf is applied over a coating of gesso, with giltwood the gold leaf is applied direct to the surface, or over a coat of linseed oil gold leaf adhesive.
  
  Most gold-finished mirrors will be gilded, whereas furniture with gold highlights will have the gold applied through the giltwood method.
