How is Glue Made
Glue is an adhesive substance used for bonding various materials. The production process involves breaking down collagen, a protein found in the connective tissues of animals, and transforming it into a sticky substance. Although multiple sources of collagen exist, such as bones, hooves, and hides, the primary animal used for glue production today is cattle.
The process of making glue begins with obtaining raw materials rich in collagen, typically from animal parts such as bones, hooves, and hides. In some instances, fish or dead horses can be used as collagen sources. These materials are then treated with chemicals, such as lime, to break down the proteins and remove any unwanted substances like fat and grease.
Once the materials are properly treated, they undergo a rendering process whereby they are boiled in water. This boiling process helps to extract the collagen from the animal parts, creating a gelatinous mixture. The liquid is then cooled and strained to remove any remaining debris or impurities.
As the strained liquid cools, it starts to solidify, forming a sticky substance called animal glue. To obtain the glue in different forms and concentrations, the mixture is dried and processed further. For certain industries and applications, the glue may be blended with other chemicals to modify its properties and enhance its performance.
While historically, horse-derived glue was more common, its production has declined significantly over time. As cattle are now more commonly used for glue production, the term “glue factory” as a reference to sending dead horses for glue production is less accurate today. The shift to using cattle and other animals has mainly been driven by the availability of these animals and the extraction of collagen from multiple sources, including fish and rabbits.
In conclusion, glue is primarily made by extracting collagen from animal parts like bones, hooves, and hides, through processes such as boiling and rendering. Cattle are the most common source for glue production today, but alternative sources, including fish and horses, can still be utilized.
