How is Horse Glue Made?
Delving into the Production of Horse Glue
One of the oldest and most versatile adhesives known to man is horse glue. It has been used for centuries and has proven to be a reliable resource in a range of applications, from woodworking to art conservation. The process of making horse glue involves several steps that are carefully followed to produce the highest quality adhesive. In this section, we will take an in-depth look at how horse glue is made. But before we dive into the steps, let’s explore the origins of this ancient adhesive.
Step 1: Preparation and Stewing
During the first step of horse glue production, the raw materials are prepared and cooked through a process called stewing, which can take up to several hours. The raw material, usually horse hooves and bones, is washed and sliced into small pieces, and then soaked in water or steam for a few hours to soften them.
After soaking, the raw material is transferred to a large pot and boiled to create a gelatinous mixture. During this stage, the mixture is regularly stirred to prevent it from burning. Once the raw materials have broken down into a liquid form, they are cooked for several hours. Remember that the longer the mixture cooks, the stronger and clearer the glue will become.
The mixture is then allowed to cool, and strained several times with a fine mesh or cheesecloth to remove any impurities. This is a crucial step in the process as any impurities that are left in the glue can affect its quality and performance.
Below is a table outlining the steps involved in the preparation and stewing stage of horse glue production:
| Step | Description |
|---|---|
| Preparation | Raw materials are washed and sliced into small pieces |
| Stewing | Raw materials are placed into a pot with water and boiled for several hours until they become a gelatinous mixture |
| Straining | Mixture is allowed to cool and strained several times with a fine mesh or cheesecloth to remove any impurities |
It is important to note that the quality of the raw materials used can affect the quality of the glue produced. High-quality raw materials such as bones and hooves from young horses can produce a stronger and clearer glue compared to those harvested from older horses. Additionally, the materials must be sourced ethically and sustainably.
Paper glue is another type of adhesive that is commonly used in crafts and woodworking, but it is made through a different process using different raw materials and chemicals.
Step 2: Straining and Clarifying
After the initial preparation and stewing of horse hides for glue making, the next step is straining and clarifying the mixture. This process is crucial because it removes any impurities or leftover tissue that may not have fully stewed.
Step 2: Straining and Clarifying Process
1. Pour the mixture into a cheesecloth-lined strainer over a large pot.
2. Allow the mixture to drip through the cheesecloth, collecting any debris in the cloth.
3. Heat the strained mixture over a fire or stove until it reaches a temperature between 140-165°F.
4. Skim the top layer of the mixture to remove any impurities that have risen to the surface.
5. Let the mixture settle for a few hours or overnight to allow any remaining debris to sink to the bottom.
6. Carefully pour off the clear glue liquid, leaving any sediments at the bottom.
7. Clarify the liquid glue further by adding egg whites to the mixture. The egg whites will bond to any remaining impurities, which can then be skimmed off the surface of the mixture.
8. Pour the clarified glue into a container and let it cool and solidify.
It’s important to note that the process of straining and clarifying can take several hours and requires close attention to detail to ensure that the end product is pure and of high quality.

Step 3: Setting and Drying
After the glue has been boiled and strained, it is time for Step 3: Setting and Drying. This step is crucial to ensure that the horse glue will be able to form a strong bond once it is applied to an object. Here is a breakdown of the setting and drying process:
- First, the glue is typically set overnight to let it cool and solidify. During this time, it will often thicken and develop a gel-like consistency.
- Once the glue has set, it can be reheated to make it liquid again. This is necessary because the glue needs to be liquid to apply it to an object.
- Next, the object to be glued is prepped by cleaning and abrading the surfaces to be joined. This is important to ensure that there is good contact between the glue and the object.
- Then, the glue is applied to one surface of the object, and the two surfaces are pressed together.
- Finally, the glue is left to dry completely. This can take anywhere from a few hours to a few days, depending on the size and nature of the object being glued. It is important to be patient and let the glue dry completely before putting any stress on the joint.
It is important to note that horse glue dries slowly compared to some other types of adhesives, but it forms a very strong bond. This is particularly true for organic materials such as wood, leather, and paper. However, horse glue may not be the best choice for bonding metal or plastic, as it may not adhere well to these materials.
The process of setting and drying horse glue requires patience and attention to detail, but the result is a strong and long-lasting bond. It is no wonder that this ancient adhesive has been used for centuries in applications ranging from woodworking to bookbinding.
