Saresh Glue Flakes is a type of protein-based adhesive made from processed animal hides and bones. It is available as dry flakes or pearls that are dissolved in hot water to form a working adhesive. It has been used for centuries in bookbinding, woodworking, and furniture making due to its excellent adhesion to porous surfaces, reversibility (joints can be opened with heat or moisture), and non-toxic nature. In India, it remains the preferred adhesive for traditional bookbinding and certain woodworking applications.
