Hoof glue is a form of animal glue made by boiling down the hooves of ungulates into partially hydrolyzed keratin. It is not to be confused with hide glue.
Hoof glue applications include stiffening bow strings, adhering fabric to wood, stiffening fabric, and sealing glass window frames and ceramic containers. Hoof glue is still used today in cabinetry and other fine woodworking projects where the joints must be capable of disassembly. [1]
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. Once melted, it is necessary to heat the glue substance until it is the required consistency – thin hoof glue can be used to stiffen fabrics; thicker glue is used in cabinetry.
The storable form of hoof glue is a hard block of resin-like material. To use it one would break off a suitably sized chunk 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 coating to stiffen and strengthen cordage, such as chair backs and seats. Hoof glue is not waterproof, it can be dissolved by water, so moisture or even high humidity will affect it. But hoof glue does not become brittle when dry; it retains some flexibility, thus making it ideal for applications where some give in the joint or covering is required.
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation.
A horseshoe is a product designed to protect a horse hoof from wear. Shoes are attached on the palmar surface of the hooves, usually nailed through the insensitive hoof wall that is anatomically akin to the human toenail, although much larger and thicker. However, there are also cases where shoes are glued.
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board.
Joinery is a part of woodworking that involves joining pieces of wood, engineered lumber, or synthetic substitutes, to produce more complex items. Some woodworking joints employ mechanical fasteners, bindings, or adhesives, while others use only wood elements.
A wetsuit is a garment worn to provide thermal protection while wet. It is usually made of foamed neoprene, and is worn by surfers, divers, windsurfers, canoeists, and others engaged in water sports and other activities in or on the water. Its purpose is to provide thermal insulation and protection from abrasion, ultraviolet exposure, and stings from marine organisms. It also contributes extra buoyancy. The insulation properties of neoprene foam depend mainly on bubbles of gas enclosed within the material, which reduce its ability to conduct heat. The bubbles also give the wetsuit a low density, providing buoyancy in water.
The hoof is the tip of a toe of an ungulate mammal, which is covered and strengthened with a thick and horny keratin covering. Artiodactyls are even-toed ungulates, species whose feet have an even number of digits; the ruminants with two digits are the most numerous, e.g. giraffe, deer, bison, cattle, goat, pigs, and sheep. The feet of perissodactyl mammals have an odd number of toes, e.g. the horse, the rhinoceros, and the tapir. Although hooves are limb structures primarily found in placental mammals, hadrosaurs such as Edmontosaurus possessed hoofed forelimbs. The marsupial Chaeropus also had hooves.
A lap joint or overlap joint is a joint in which the members overlap. Lap joints can be used to join wood, plastic, or metal. A lap joint can be used in woodworking for joining wood together.
Neatsfoot oil is a yellow oil rendered and purified from the shin bones and feet of cattle. "Neat" in the oil's name comes from an Old English word for cattle. Neatsfoot oil is used as a conditioning, softening and preservative agent for leather. In the 18th century, it was also used medicinally as a topical application for dry scaly skin conditions.
Frame and panel construction, also called rail and stile, is a woodworking technique often used in the making of doors, wainscoting, and other decorative features for cabinets, furniture, and homes. The basic idea is to capture a 'floating' panel within a sturdy frame, as opposed to techniques used in making a slab solid wood cabinet door or drawer front, the door is constructed of several solid wood pieces running in a vertical or horizontal direction with exposed endgrains. Usually, the panel is not glued to the frame but is left to 'float' within it so that seasonal movement of the wood constituting the panel does not distort the frame.
Animal glue is an adhesive that is created by prolonged boiling of animal connective tissue in a process called rendering. In addition to being used as an adhesive, it is used for coating and sizing, in decorative composition ornaments, and as a clarifying agent.
Rabbit-skin glue is a sizing that also acts as an adhesive. It is a type of animal glue that is essentially refined rabbit collagen. The glue has been used for centuries for stretching and priming canvases for oil painting. It has also been an ingredient in traditional gesso.
A countertop, also counter top, counter, benchtop, worktop or kitchen bench, bunker is a raised, firm, flat, and horizontal surface. They are built for work in kitchens or other food preparation areas, bathrooms or lavatories, and workrooms in general. The surface is frequently installed upon and supported by cabinets, positioned at an ergonomic height for the user and the particular task for which it is designed. A countertop may be constructed of various materials with different attributes of functionality, durability and aesthetics, and may have built-in appliances, or accessory items relative to the intended application.
Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues. They worked by solidifying as they dried. Later, glues were made from plant starches like flour or potato starch. When combined with water and heated, the starch gelatinizes and forms a sticky paste as it dries. Plant-based glues were common for books and paper products, though they can break down more easily over time compared to animal-based glues. Examples of modern wood glues include polyvinyl acetate (PVA) and epoxy resins. Some resins used in producing composite wood products may contain formaldehyde. As of 2021, “the wood panel industry uses almost 95% of synthetic petroleum-derived thermosetting adhesives, mainly based on urea, phenol, and melamine, among others”.
Kopytka are a kind of potato dumpling in Polish, Belarusian, and Lithuanian cuisines. They are similar to Italian gnocchi.
Kluski is a generic Polish name for all kinds of soft, mushy dumplings, usually without a filling.
A horse hoof is the lower extremity of each leg of a horse, the part that makes contact with the ground and carries the weight of the animal. It is both hard and flexible. It is a complex structure surrounding the distal phalanx of the 3rd digit of each of the four limbs, which is covered by soft tissue and keratinised (cornified) matter.
A hoof boot is a device made primarily of polyurethane and is designed to cover the hooves of a horse as an alternative to, and occasionally in addition to, horseshoes. Hoof boots can also be used as a protective device when the animal has a hoof injury that requires protection of the sole of the hoof, or to aid in the application of medication. There are many different designs, but all have the goal of protecting the hoof wall and sole of the horse's hoof from hard surfaces, rocks and other difficult terrain.
Edge banding or edgebanding is the name of both a process, and an associated narrow strip of material. It is used to create durable and aesthetically pleasing trim edges during finish carpentry. The method is used to cover the exposed sides of materials such as plywood, particle board, or MDF. This increases durability and creates the appearance of a more solid or valuable material.
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus, which locks major joints in the limbs, allowing horses to remain standing while relaxed or asleep. The limbs play a major part in the movement of the horse, with the legs performing the functions of absorbing impact, bearing weight, and providing thrust. In general, the majority of the weight is borne by the front legs, while the rear legs provide propulsion. The hooves are also important structures, providing support, traction and shock absorption, and containing structures that provide blood flow through the lower leg. As the horse developed as a cursorial animal, with a primary defense mechanism of running over hard ground, its legs evolved to the long, sturdy, light-weight, one-toed form seen today.
Furniture repair is the craft of making broken or worn furniture usable again. It may include the preservation of old furniture, which is referred to as restoration. The craft of furniture repair requires a number of different skills including woodworking, metalworking, wood finishing, caning (furniture), woodturning, and upholstery.
