Leave the flakes in water for at least 24 hours before usage. Delete water in excess by decanting, then melt the glue by bain-marie cooking, using the GILDER'S POT. Differently from other animal glues it will not raise considerably its volume. It is mainly used to stick the gold leaf on bole.

Apply the glue delicately on bole with a single pass, otherwise bole can be re-dissolved and removed by the brush. Immediately after pick up a piece of the golden leaf with the aid of a Gilder's Tip, and gently approach it to the support to make it adhere.
