Animal Glue: A Traditional Adhesive for Centuries

Discover the History and Benefits of Animal Glue

A Natural Adhesive with a Long History

Animal glue has been a vital woodworking adhesive for millennia, predating the advent of synthetic glues. Derived from animal collagen, a protein found in hides, bones, and other animal byproducts, animal glue offers unique properties that have stood the test of time.

Types of Animal Glue

Various types of animal glue exist, each with its characteristics. Hide glue, the most common, is extracted from cattle or horse hides. Gelatin glue is made from animal skin and bones, while fish glue is obtained from fish bladder membranes. Rabbit skin glue and bone glue are also popular varieties.

Versatile Bonding Capabilities

Animal glue exhibits excellent bonding capabilities for a range of materials, including wood, paper, fabric, leather, and even metal. Its adhesive strength comes from the collagen fibers that form when the glue dries, creating a strong and flexible bond.

Hot Glue or Liquid Glue

Animal glue is available in both liquid and solid forms. Liquid hide glue, made from collagen extracted from animal hides, is commonly used in woodworking and restoration projects. Solid animal glue, known as "hot glue," is dissolved in water or vinegar before use, offering greater flexibility.

Traditional Woodworking Applications

Animal glue has been the primary adhesive choice for many types of woodworking, particularly in the creation of musical instruments and furniture. Its reversibility allows for the easy repair of joints, making it ideal for delicate restoration projects.
