Real leather is used in various fields of human activity since ancient times because back then animal skins were needed for protection from the cold, besides it was the most available material of all. Initially, they were processed using the smoke from a fire, but it could not maintain the integrity of the skins for a long time.
Then the man began to use various plant substances to make the skin stronger, more elastic and keep it for a longer period. Now the world produces a huge number of varieties of leather, each of which is suitable for a particular purpose. Accordingly, depending on the desired result, do it in different ways. In particular, there is a method of treatment as a crust, about which more will be discussed in this article.
The Processing of natural leather usually consists of three stages. First, conduct preparatory actions, when the animal skin is cleaned, soaked in various solutions, treat the hair and fat layer and soften. The most popular and convenient types – it is the skin of cattle, of which the most common veal, pork and sheep. But at all times was popular and the skins of exotic animals-snakes, crocodiles, because of their unusual appearance.
Now the products of these materials also remain popular, but because the hunting of the reptiles were previously so common that they were under the threat of extinction, modern manufacturers often use artificial leather or genuine imitation of the required figure, fortunately, modern technologies of processing allow it.

The Next step – tanning – is to give the skin resilience, strength and elasticity, basic properties of high quality natural leather. At this stage the material is soaked in special solutions which contain chromium, aluminium, vegetable and synthetic tanning agents or combinations thereof. Suede, for example, obtained by the treatment of the skin fatty acids. At the end of the operation it has the form of finished semi-finished product, but additionally, depending on the variety, can be performed and other processing.
At the last stage of the skin surface by various methods to impart an attractive appearance to its obverse surface-planing, coating (i.e. the surface) or deep staining, stamping, polishing and others.
Over the years, the development of leather craft emerged a huge number of types of leather: saddle, Laika, crust leather, Russia leather, kid, suede, shagreen, suede, etc.
So, for the manufacture of haberdashery products (mainly gloves) use a husky, which is created from the skins of lambs and after chrome tanning is soft, flexible and very pleasant to the touch. Also they are made from suede, the front surface of which is covered with low soft pile. Due to this surface features it is hard to clean, gets dirty faster, it can form stains when wet, and wears out faster than other types of leather. Therefore, usually the product of suede is not intended for everyday use, besides, they have a very winning appearance – stylish and noble.
Bags, wallets and belts < / span>Made out of UFTI (the so-called “Russian leather”), which is of varying thickness and properties depending on the material from which it is made – this is usually the skins of cattle. In any case, this kind of leather is highly durable and soft, these properties yuft receives after the treatment of plant components. Men's belts are sometimes made of saddle – it's a very tough skin, which suffers from the increased durability.
To create shoes apply a variety of skin types, depending on purpose of the Shoe. Most often it is smooth its variety – it's expensive high quality products, as the material has high performance. Shoes and boots often made of patent leather, which does not allow the feet to breathe, but it looks expensive and neat. Also for shoes use suede and other types.
For jewelry craftsmen use either the soft or thin skin, or if you want to leave on the product, impression – more rigid, for example, Russia leather, or saddle.
We should also remember the parchment, which in the modern world use much less than before - in bookbinding, jewelry and musical instruments, in one word – in specific activities. In the past it was the main material for the creation of manuscript books.
Crust-it's a calque from the English word "crust" which translates as “peel”.
After the initial sorting of the skins of cattle and they begin to macerate. Crust here is distinguished by several features: it is processed using large amounts of chromium and water, allowing you to make the skin elastic and soft at the same time, and, besides, it is necessary to comply with environmental requirements.
In the next stage, the skin painted by drum dyeing. Thanks to modern methods, the dye penetrates into the skin and gives, thus, through staining. For this reason, there is no fear that the upper painted layer will crack.
On the reverse side of the workpiece can stay the print drum grid because of the specificity of the method of prokras. The front surface is not finished, so natural skin krast has her natural figure, from-for what quality crust is sometimes difficult to distinguish from smooth leather. Moreover, no surface treatment allows to subsequently avoid many of the disadvantages associated with the destruction and detachment. Also, the leather has high resistance to water, which occurs at the stage of tanning.
The Special qualities of the skin krast allow you to apply it in the production of a variety of items. This material is quite durable but also malleable and lightweight, and moreover, it has a long life. Therefore, it is used in the manufacture of bags, shoes, accessories, a variety of stationery and even furniture. In addition, the master in charge of the work on the skin, among other types, choose the skin crust for embossing, as its texture is best suited for this finish.
To take Care of this kind of skin is necessary, given the characteristics of its surface. Wash crust does not make sense, since it's waterproof, and only lost some of its strength and aesthetics. But it can be cleaned of dust with a dry scraps, and if the product appears the dirt – better to remove it with a slightly alkaline cleaning solutions, applied on a soft sponge. After wet cleaning, the product should be wiped away. Periodically you should use to lubricate the skin crust by special means which will retain the elasticity and strength of material.
The Small scratches that inevitably occur with frequent use of the product, crust is able to heal itself due to the fact that there is a natural pattern of the skin-from friction scratches are aligned and eventually disappear completely. On bends and in areas of friction skin color may darken, giving the appearance of antiquity and quality.
