Animal glue, also known as hide glue or gelatin glue, refers to a type of adhesive substance derived from animal collagen and other connective tissues. It has been used for centuries as a versatile and reliable adhesive for a range of applications. The glue is obtained through a process of heating and processing these animal materials, typically sourced from the skins and bones of animals such as cattle, horses, and rabbits.
Animal glue has unique properties that make it particularly suitable for various purposes, including woodworking, bookbinding, and musical instrument construction. It is characterized by its strong bonding capacity, flexibility, and compatibility with porous materials like wood, paper, and leather. Animal glue is soluble in water, allowing easy application and reactivation by heat or moisture, making it convenient for repairing or repositioning objects.
Historically, animal glue has been widely used in the production of furniture, woodworking joints, and as a sizing material for fabrics. It has also played a crucial role in bookbinding, providing a durable and secure attachment for paper and leather bindings. Additionally, animal glue has been utilized in the construction of musical instruments, particularly for holding strings in place and ensuring their proper resonance and vibration.
While synthetic adhesives have become more prevalent in modern times due to their convenience and ease of use, animal glue still holds its place in traditional craftsmanship and restoration work, appreciated for its authentic qualities and compatibility with historical techniques.
The word "animal glue" is derived from the Latin word "animalis", meaning "of or pertaining to animals", and the Old French word "glu", which means "glue". The use of animal glue dates back to ancient times when it was made by boiling animal hides, bones, and connective tissues to extract the gelatinous substance. Animal glue has traditionally been used as an adhesive for various applications, such as woodworking, bookbinding, and painting.
