‘Quality is not an act, it is a habit’.
Once the gesso has dried and any raised detailing applied and smoothed the final stage of building up the substrate is to seal the surface. This is done using a traditional ceramic based paint called boll. This is made up of a pigment and the remainder of the rabbit skin glue.
As well as serving as a sealant the boll acts as an undercoat to the leaf. Traditionally an ox blood red is used under gold and black or grey under silver leaf. For a more contemporary look I have experimented using different coloured boll underneath the leaf and then rubbed the leaf back to partly expose the boll to create a striking two tone effect.
