When asked how he achieved this, he replied, I whisper in the horse’s ear: Roses are red, violets are blue. They take fat and bone trimmings from grocery stores, waste scraps from restaurants, and dead animals.

You’ve probably heard that horses are killed in order to be made into glue. Horses contain high levels of collagen which is a key ingredient in most animal-based glue.
The surfaces can be separated again with clean surfaces You can apply a new layer of glue on top of an old layer You can correct an irregular fit by heating up the glue It produces a tight joint that does not bend over time When you’re working with glue that isn’t made from animals you will typically not have these advantages.
Some factories might kill a perfectly good horse in order to turn it into glue. So you don’t need to worry that your horse will suddenly be caught and turnedintoglue.
This way the animal is being put to great use after it can no longer live a good life. This wasn’t something people gave a lot of thought back in the days.
We would eat the meat and try to think of other ways to utilize the bones, teeth, homes, etc. Sometimes your fingers will stick together and this sticky substance is partly the collagen that is being used in the animal glue.
Fish glue has been used for more than 10 years and it is used for glass, ceramics, wood, paper leather, and metals. In fact, several factories in Canada are using dead animals to produce sticky substances in the glue.
So we do not kill animals in large quantities in order to make glue. This is especially great for art projects and finer woodwork like cabinetry and furniture.
The horse glue is typically being produced in France and other countries in Europe. So if we wanted to glue together two pieces of material we would have to use the collagen from dead animals.
Well, it’s actually illegal to eat horse meat in the United States. So oftentimes the dead horses are sold to foreign countries to be eaten.
But more often the dead horses are being delivered to a zoo in order to feed animals. The gummy bears are made from bones and muscles from dead animals.
As we mentioned above, we don’t use animals to produce glue to the same extent as earlier. Today the factories will typically produce glue called “polyvinyl acetate” (also known as PVA).
It would harden at specific temperatures which was a good thing when you wanted to separate the two pieces. The ingredient mix is secret, but they have specifically stated that they do not use animal collagen anymore.
Other people argue that the laughing cow on Elmer’s glue bottles is a symbol of happy animals that got to live. Because they found other and better ways of producing glue more efficiently the cattle can now keep smiling.
Yes, it’s true not only horses but several other animals are brutally murdered to make glue. Yes, Glue made from horse parts like hooves and bones.
These parts are rich in collagen which is the main component of Animal glue. This glue is sticky in wet form and very hard when dried.
Horses used for thousands of years but still some misconceptions about the production of glue need to be solved. The practice of deriving glue from horses is several thousand years old and no one really knows how exactly old it is.
So, the “human nature” got curious, and they started experimenting and this led to the foundation of animal glue. And then the United States of America decided to follow the trend by opening a glue factory in 1899.
The glue making process is fairly simple as it is made by boiling the animal hide, hooves, bones, and tendons. Bones, tendons, and skin releases collagen, a substance that when cooked turns into glue.
The demand for animal glue by professional craftsmen, designers, and manufacturers has kept it alive. This is the reason why we keep hearing that the horse is being sent to the glue factory.
They do not necessarily have to be murdered to turn into the glue, even a dead horse that is of no use is useful. Unfortunately, it is now only used to fix broken furniture and stringed musical instruments.
Even if it is strong, glued parts can still be taken apart as heat and humidity soften it. 120F heat and 75%RH humidity is an ideal environment to melt the glue.
Hot glues are heated or sometimes mixed with boiling water to bring it to ready-to-use form. But this is the least desired form of horse glue as the risk of bacterial and fungal growth makes it sound like a waste of money.
You can make your own horse glue if it’s easy for you to arrange the ingredients Trim the non-desired parts(hair or meat particles) and cut it into the smaller pieces as small as you can.
Find the most hated pot you have in the kitchen as it is going to ruin the plot. The presence of water may make the glue lose its stickiness.
To check whether it’s done or not, put it on your finger, place your thumb on it and see if it sticks to it or not. Keep breaking the piece every day until the crumbles dry off completely.
But make sure you have a scented candle or something as the mixture starts boiling it produces a very strong unpleasant smell so scented candles and room fresheners would be a great help. As the factories are making the commercial-grade glue on a large scale, so they follow a different procedure.
The extracted collagen is concentrated and converted into the noodles form then it is sent for milling and the rest of the process is performed there. As the glue requirements increased with the time the unavailability of fresh raw material led the makers to wonder and that’s how they found the cheap alternatives.
As the cheap alternatives were readily available and the fresh raw material(Bones, teeth, skin, tendons) is impossible to store and then the synthetic glue is doing a pretty good job so it got expensive and started disappearing silently from the world’s map. It gets shrunk and darker with time, further climate change, humidity is also the biggest threat to your glued furniture and artwork.
If you can find a ready-made horse glue or could arrange the ingredients to make you own this is what you need to know. Horsehide glue is a popular glass mender for it’s shrinking ability.
It hardens and shrinks, bringing the shattered piece closer that even the evidence of its brokenness disappears. Glass artists are also still a fan of animal glue as it has helped in creating many masterpieces.
A warm water bath is needed to turn the glue into magic as it can only be applied when it is hot. As mentioned above it works only when it is hot so it can only be applied with a brush or spatula.
Running for a brush or spatula when the glue is in ready to use mode is an unpleasant situation after all. The parts(bones, tendons, skin, etc) that produce the substance called collagen are boiled to make the glue.
Because of its previous formulation, it is still misunderstood as an animal glue even though they have changed the ingredients several years ago. It may not or may turn out a little weaker than the glue made in the factory but it will still be strong enough to do the job for you.
Boiling the ingredients at a certain temperature leaves the glue in the pot. It is not popular for office and regular school projects but for glass artists and Carpenters it is still as precious as Diamonds.
A horse that has just died can also be purchased for this purpose but killing to turn into glue is more common. Rubbing a vinegar-soaked cotton pad and then rinsing it off with mild soap will help you get rid of this problem.
No doubt, horse glue is strong and handy but it is expensive and takes a lifetime to develop. Frequent heating or overheating makes it completely useless.
This is the reason why it is advised to take all the precautions seriously when it comes to using horse or animal glue. All hide glues make a stronger bond with natural fibers.
Even though it is considered a permanent solution but still moisture, steam, and heat can undo the action performed. The first-ever horse glue manufacturing industry was opened in Holland in 1700.
Horse glue was a popular stationery item till the 18th century. Cartilage, tendons, and ligaments make excellent quality horse glue.
Dead horses are as useful for glue factories if they are handed over to them at the right time. Skin, tendons, and bones are used to make the strongest and longest-lasting glue and this has been in practice for the longest time even though history has lost count.
Cattle and pigs are also used to make glue but horse are preferred as they produce collagen in large amounts. I love to solve equine health care issues and note down in the form of research papers.
I have written hundreds of equine health care, accessories, names, and history-related blogs. My equine related work is watering a lot of horse-related magazines and blogs.
This allows horse glue to be applied, removed, reapplied, and layered as many times as needed. No matter if it is because of a mistake or alterations, the glue completely melts to reveal a clear surface.
Most animal glues in history were made form horses and cattle because they were simply there. They were a big part of our daily lives, and once they die, they would become a free source of collagen.
It was a lot more convenient to hand over Bessie or Thunderbolt, than to hunt down a hundred rabbits. On top of it all, the production process of this glue is complicated, so factories often opt to make other types of adhesives.
The joints horse glue creates brittle, which can be an asset in the production of musical instruments. Horse glue also works as its own clamp, so there is no need to apply them on delicate violin wood.
There are quite a few farms and ranches around the world that grow horses solely for their meat, hair, and other parts. However, the vast majority of horses that are used to make glue have died a natural death or were euthanized.
When a horse is kept for racing, ranching, or as a pet, it is up to the owner what will happen to them after they die. There are multiple guidelines for safe disposal of the remains that are designed to show both the respect for the animal and address overall health and safety.
In most countries, it’s illegal to sell off the remains to a glue factory without the signed permission from the owner. The glue liquor is heated many more times before it’s left to cool down and then chopped into pellets.
There are records of humans using horse glue from 6,000 years ago, but we don’t know how they made it back then. A thousand years ago in China, it was mixed with pigments to produce a very durable paint.
The Terracotta Army, a collection of figures that were buried with the first emperor of China Qin Shi Huang, was painted using this mixture. Throughout centuries in Europe, horse glue was used for a similar purpose, as well in the production of musical instruments.
Animal glue factories managed to survive through the Great Depression but soon fell out of favor with the invention of synthetic adhesives. And the chances of emergence are very low since contemporary consumers are not to keen on the origin of the main ingredient.
Horsehair is used in the production of violin bows, paintbrushes, jewelry, fishing equipment, and upholstery textiles. It is used to create a filter that bleaches cane sugar, but it doesn’t end up in the final product.
It wasn’t until years later I learned the truth about whether or note glue is made from horses. Glue was originally made from animal collagen which can be found in skin, bone, and tissue.
Native Americans used to make glue from hides and hooves of animals. In early America it was common practice for ranchers to send unwanted horses to be processed at glue factories.
In fact, while it originally included milk in the ingredients, the traditional school glue you are used to is now all synthetic. Elmer’s Glue website specifically states that their product is made from 100% synthesized (man-made) ingredients.
The process of extracting collagen from dead animals is time-consuming and much more costly. There are currently no horse slaughter plants operating in the United States.
American horses are, however, sometimes transported to countries like Mexico and Canada to be slaughtered. The types of glues that are made from animals utilize the collagen found in the horse.
It can be extracted from hooves, skin and bones by boiling the body parts. In fact, this video does a wonderful job of explaining why animals were used for glue in the past and why that practice isn’t as common now.
Cows would be most common because of the numbers but some glues are made from rabbit and fish as well. Collagen is a key protein in connective tissues (cartilage, tendons, ligaments) as well as hides and bones.
It’s also the key ingredient in most animal glues, as it can be made into a gelatin that’s sticky when wet but hardens when it dries. Other adhesives were made from egg whites, tree sap, tar, and beeswax, which the ancient Romans used to caulk the planking in ships.
For fish glue, Theophilus recommended the bladder of the sturgeon, but alternatives included and “the bones of the head of the wolf fish.” The first commercial glue factory, started in Holland in the early 18th century, used animal hides. Animal glue, popular for thousands of years, has fallen out of fashion in recent decades.
Over the second half of the 20th century, synthetic glues have become more advanced, as they are cheap, uniform in quality, and have longer shelf lives. Bookbinders are fond of them because they’re slow to set, allowing binders plenty of time to work.
Only deceased horses that are taken to a rendering plant incur this fate. Others are burned, left out for scavengers, sent to zoos to feed the wild animals, or cremated.
Sending a horse to auction, due to the sole nature of the transport and handling methods used, is at the current time inhumane. Humane euthanasia for any horse, regardless of the reason, is by injection done properly by a veterinarian or by gunshot or captive bolt to the head performed by someone that is knowledgeable of the specific spot the skull must be penetrated.
Gawd I hope not....I made my sister eat it the other day.....I told her it was ranch dressing....lol In the old westerns and Bugs Bunny cartoons that pretty much formed my thought processes as a child, they would always threaten to send the old horse to the glue factory.
And (b) if so, what's the recipe for making horse glue ? A. Yes this used to happen very often a while ago but nowadays they just get a few horses that have been killed or died of natural causes, I know that sounds a bit harsh but it's better than some things.
Horses are sold to rendering house if deceased and a slaughterhouse if alive. Animal (origin) glue is made from connective tissue, found in hoofs, bones, tendons, ligaments, and cartilage in vertebrate animals.
It generally is not used for everyday glues, such as white paste used in school projects. Animals (including horses) are rendered down for animal food (such as dog food) and for nonedible items, such as soap and various lubricants.
Most glue is made out of other product, such as oils, etc. But now the horse will go from auction to Mexico or Canada where it's slaughtered.
Most glues these days are made with adhesives, not horses. In the 1960's Northampton there used to be a glue factory and it was dead animals that they used.
