This type of glue has been in use for many centuries, and still preferred by craftsmen for restoration and new work. This is a192-gram weight hide glue, formulated for veneering. It has the advantage of being reversible, or repairable if the veneer surface is ever damaged or needs to be replaced. It is mixed 50% with water, allowed to sit for a couple of hours, then melted in a double boiler at 140 degrees for 1 hour before use. Stir in a small amount of fresh water when glue thickens to much. One preferred way to use hide glue for veneering is to spread the glue onto the core, apply the veneer after a few minutes, put a sheet of thin plastic over the veneer, canvass, and then press the veneer tight onto the core by clamping a hot (150 to 160° F) metal platen over surface to re-liquefy and spread the glue between the core and veneer. Clean up with warm water.
