Horses, with their sturdy hooves and tough hides, were particularly sought after for this purpose.

The process of making glue from horse hooves was labor-intensive but effective. The hooves were collected and thoroughly cleaned to remove any dirt or debris. They were then boiled for several hours until the collagen proteins broke down and became gelatinous. This gelatinous substance was strained and cooled, resulting in a sticky, adhesive material that could be used for a variety of purposes.

One of the key advantages of using horse hooves in glue production was their high collagen content. Collagen is a fibrous protein that provides strength and flexibility, making it an ideal ingredient for creating adhesive substances. Horse hooves also contained keratin, a protein that increased the adhesive properties of the glue.

Glue made from horse hooves was particularly valued in woodworking and bookbinding industries. The strong adhesive properties of the horse glue allowed for secure and long-lasting bonds, making it an essential tool for craftsmen and artisans. Furthermore, the glue could be easily applied, allowing for precise and accurate work.

However, it’s important to note that horses were not the sole source of glue during this time. Other animals, such as cattle and pigs, were also used for glue production. Each animal had its unique properties and advantages, and glue manufacturers often utilized a combination of different animal parts to create the desired adhesive.

The use of horses in glue production began to decline in the late 19th century with the rise of industrialization and the development of synthetic adhesives. Synthetic glues offered greater convenience, consistency, and affordability compared to traditional animal-based glues. As a result, the demand for horse glue diminished, and manufacturers shifted their focus towards more modern alternatives.

Today, while horses are no longer a primary source of glue, the historical use of horses in glue production serves as a testament to their versatility and the valuable resources they provided. It is a fascinating glimpse into the ingenuity of our ancestors and the ways in which they utilized the natural world to meet their needs.
