Throughout history, various materials have been used to create adhesives, with some surprising sources making their way into the production process. One such intriguing historical ingredient is animal glue, particularly that derived from horses. This begs the question: do they still make glue from horses in modern times?
A Glimpse into the Past: Animal Glue and Horses
The Traditional Use of Horse Glue
In the past, animal glue was a widely used adhesive, particularly in woodworking, bookbinding, and even in the manufacture of certain types of paper. Horse glue, specifically, was prized for its strength and durability. The process involved boiling down horse hides and hooves, extracting the collagen-rich gelatin that formed the basis of the adhesive.
This traditional method, though effective, presented certain challenges. Sourcing animal hides and hooves required significant resources, and the process itself was labor-intensive and could produce a strong odor.
Do They Still Make Glue From Horses?
The image of a horse-drawn carriage might conjure up thoughts of a bygone era, and the idea of using horse parts to make glue might seem equally antiquated. But the truth is, the connection between horses and glue is a surprisingly long and complex one. While the use of animal-derived glue has declined significantly in modern times, it’s not entirely gone. This article delves into the history of horse glue, explores the reasons behind its decline, and examines whether it’s still being produced today.
A Historical Perspective: Horse Glue Through the Ages
For centuries, glue made from animal collagen, primarily from hides and bones, was a staple in various industries. This type of glue, known as “animal glue” or “gelatin,” was prized for its strength, durability, and versatility.
The Role of Horses in Glue Production
Horses, with their robust hides and bones, played a significant role in the production of animal glue. The process involved boiling down horse hides and bones in water to extract the collagen, which then solidified into a glue-like substance when cooled. This glue was used in a wide range of applications, from bookbinding and woodworking to papermaking and even as a food thickener. (See Also: Do Wolves Attack Horses)
The Decline of Horse Glue: Technological Advancements and Ethical Concerns
The 20th century witnessed a dramatic shift in the glue industry. The development of synthetic glues, such as polyvinyl acetate (PVA) and epoxy, offered several advantages over animal-derived glues:
- Superior Strength and Durability: Synthetic glues often exhibited greater tensile strength and resistance to moisture and heat compared to animal glue.
- Faster Drying Time: Synthetic glues typically dried much quicker, making them more efficient for industrial applications.
- Consistency and Predictability: Synthetic glues could be produced with greater consistency and precision, ensuring uniform performance.
Moreover, ethical concerns surrounding the use of animal products in glue production gained traction. Animal welfare groups raised concerns about the sourcing and treatment of animals used for glue production, leading to a growing demand for cruelty-free alternatives.
The Modern Landscape: Is Horse Glue Still Made?
Today, the production of horse glue has become extremely rare. While some niche markets may still utilize animal-derived glues for specific applications, the vast majority of glue used in modern industries is synthetic.
Limited Production and Specialized Uses
A few specialized manufacturers may still produce animal glue, including horse glue, for specific purposes. These uses often involve traditional crafts, restoration work, or applications where the unique properties of animal glue are essential.

- Bookbinding: Some traditional bookbinders prefer animal glue for its archival quality and ability to create strong, flexible bonds.
- Musical Instrument Repair: Animal glue is sometimes used in repairing antique musical instruments due to its compatibility with aged materials.
- Art Conservation: Animal glue may be employed in the restoration of artwork, particularly when dealing with delicate materials or historical adhesives.
Key Takeaways: A Legacy of Innovation and Change
The story of horse glue highlights the evolution of the glue industry, driven by technological advancements and changing societal values. While horse glue once played a vital role in various industries, its use has significantly declined due to the emergence of superior synthetic alternatives and ethical concerns. Today, while limited production may still exist for specialized applications, horse glue has largely become a relic of the past.
Frequently Asked Questions About Glue and Horses
Do they still make glue from horses?
No, glue made from animal products, including horses, is very rare today. Most modern glues are synthetic and made from petroleum-based products.
What was horse glue used for?
Horse glue was primarily used for its strong bonding properties in applications like bookbinding, woodworking, and even making shoe soles. It was also used in some medical adhesives.
Why isn’t horse glue used anymore?
Several factors led to the decline of horse glue. Synthetic glues became more affordable, reliable, and versatile. Additionally, concerns about animal welfare and the availability of alternative materials contributed to its phasing out. (See Also: Are Horseshoes Good For Horses)
Are there any ethical concerns about using horse glue?
Yes, there are ethical concerns surrounding the use of animal-derived glue. Some people object to the use of animals for this purpose, particularly if it involves practices that could be considered inhumane.
What are some alternatives to horse glue today?
Modern glues are widely available and come in various types, including wood glue, epoxy, superglue, and acrylic glue. These synthetic glues offer strong bonding, durability, and are often more convenient to use.
