Gilding Grounds used with Gold Leaf
Grounds serve a two fold purpose, they act as filler if working on bare wood and as composition or genuine gold leaf is so thin, they serve to give gold a warmer colour, also if you are creating an aged finish the deep red colour will show through the gold giving a very authentic appearance as the picture on the right clearly shows.
You can use Armenian bole for this purpose, many do, but I choose to use a simple red ochre earth pigment which gives good results I feel
This ground is simply mixed with water if working with a wood or porous surface, or it may be mixed with size if you are thinking of working on a non porous surface such as glass or metal.

For those interested in using silver leaf you should note that the colour of the ground should be blue not red.
