Assist gildingt
After having slightly powdered the surface to be gilded with talc, apply the gilding size (here we used brown ale) onto the whole area or by "zones". Wait about twenty minutes and apply the gold leaves. If the size is too dry, revive it by blowing slightly with your breath on the surface of the icon... Remove the surplus of gold with a soft brush and let it dry.
Protect the golden rays with a fine layer of transparent shellac and let it dry.
