Preparation : Use a glass or a copper container to prepare the Bone Glue, do not use metallic container.
100 g of Bone Glue for 200 to 300 ml of water.
Soak the glue in cold water for 6 to 12 hours in cold water until desired viscosity. Melt using a Bain-Marie for 15 to 20 minutes, do not exceed 65°C, stir using a wooden object. With the temperature rising, a foam will appear on the surface, this means that the glue is ready to use.
Caution, never boil, the more the glue is heated, the less it will be resistant.
