Leatherworks refer to articles, particularly those of a decorative nature, made from leather. Animal hides and skins are converted into leather by soaking them in a solution of tannic acid or other chemicals. Leatherworks are typically manufactured from the hide of cattle, pigs and sheep, although exotic leather made from crocodile, snake and ostrich is increasingly in demand. International access to raw materials can be discovered from the suppliers at productpilot.com.
In leatherworks terminology, the outer surface of the hide, which contains hair follicles and sebaceous, or oil, glands is known as the grain side. Full grain leather is leather that has not been buffed or sanded, such that the surface is left intact before the surface coating is applied. No attempt is made to conceal the natural markings of the animal, variations of grain or imperfections.
Corrected, or embossed, grain leather is leather that has been buffed or sanded to remove imperfections before the surface coating is applied. The correction process inevitably wears away some of the natural grain, but a grain pattern is embossed into the surface. Corrected grain leather is typically indistinguishable from full grain leather to the naked eye.
Raw animal hides are soft and limp at high temperatures and hard and rigid at low temperatures. They are also subject to decay over time, so they are treated with a mixture of tannic acid and other chemical agents, including alum and formaldehyde, to make them durable, supple and water resistant. This process, known as tanning, alters the structure of a protein, known a collagen, in the hide to produce the desired physical properties. Modern tanning methods produce vast quantities of leather as quickly and inexpensively as possible.
