Hoof glue
From Wikipedia, the free encyclopedia
Hoof Glue is an adhesive made by boiling down the hooves of ungulates. It is a partially hydrolyzed keratin. It is a kind of animal glue.
[edit] History
Hoof glue was widely used throughout human history. The oldest known bow is 9600 years old and made using hoof glue. Animal glues have been used for things like stiffening bow strings, adhering fabric to wood, stiffening fabric, creating thin lacquers to protect valuable objects, sealing glass into frames, and sealing ceramic containers to name just a few. Hoof glue is still used today in cabinetry and other fine woodworking projects where the joints must be extremely fine if not invisible.
[edit] Formulation
The general process is to take the hooves of ungulates and break them into small chunks and then boil them in water until all the hoof material has been liquefied. An acid is then added to create a thick gel. The resultant product is then cooled and allowed to harden.
[edit] Usage
The storable form of hoof glue is a hard block of resin-like material. To use it one would break off a suitably sized chuck and mix it with hot water and allow it to melt. Once melted it can be simmered to reduce to the appropriate thickness and then applied to the object in question. Very thin glue can be used as a resin coating to stiffen and strengthen cordage, such as bow strings or chair backs and seats. Hoof glue is not waterproof.
