Animal hoof glue is derived from hoofed animals (such as horses and llamas), and is made by crushing the hooves into small pieces, boiling them until liquid, and then adding an acid to create the chemical reaction which leads to the glue formation. It is then set into a hard resin form, and this is how the glue is purchased by users. To create the liquid glue, it is then necessary to melt down the solid glue by mixing chunks into hot water. Once melted it is necessary to heat the glue substance until it meets your required consistency – thin hoof glue can be used to stiffen fabrics, whilst the thicker glue is sometimes used in cabinetry.
Animal-based adhesives which use a collagen powder are straight forward blends of sugar, glycerol, a wetting liquid (such as water) and the collagen powder itself. They may come pre-made or you may need to create the mix yourself. Rabbit-skin glue is a good example of this type of adhesive, and is usually sold in powder form and must be heated with water to create the glue consistency.
In the instance of hide glue, the adhesive itself may come in a granule or powder form which must then be added to water and heated to a relatively hot temperature to form the liquid glue. Animal hide glue must be applied to the area you are gluing while still warm. At room temperature it turns into a stiff gel and will not be strong enough to hold together the items you are adhering. As such it is important that you have the objects you are planning to glue prepared so that once the glue is at the right temperature you can get straight to work.
Vegetable-based adhesives are made from starch or dextrin powder and are mixed in with water to the right consistency.
