How to distinguish a natural skin from a leather substitute?

To distinguish a natural skin from a leather substitute very difficultly. Recently have learnt to create even a smell of the present skin. After all the new generation of artificial materials which structure includes a leather crumb, has a smell of a natural skin. Especially the Spanish and Italian manufacturers have succeeded in it. If the product is really made of natural raw materials, on it should stand (or to hang in the form of a label) the skin sign - the emblem repeating outlines of the removed skin. Artificial materials are designated by a rhombus. In firm things all cuts, as a rule, are carefully hidden inside. But nevertheless try to find open (for example, in a place of a patch of the lock, on a joint of seams). As a rule, leather substitutes have a basis, is frequent from textiles. Therefore if you see a fabric basis or individual sticking out threads, before you a bag from an artificial skin. One more possibility - whether to drip on a skin water and to look it absorbs it. If has absorbed and has darkened, that, possibly, before you a natural skin if is not present, - a leather substitute. Besides, on manufacture the technology of manufacture of skins is observed, steady dyes are used, and the furrier is engaged in selection of skins. On handicraft products very often skin slices differ on colour, a thickness and structure. In an ideal, the thickness of skins should be everywhere identical, except for those places where on STATE THAT consolidation is supposed. In general for a natural skin softness and elasticity are characteristic. Essential difference of a skin from other materials that it does not light up over fire. Try to take a skin slice over the lighted match or a lighter. You will not notice even decay. But the leather substitute will start to burn at once. Therefore if the product from a skin has got under a rain or was rumpled, it can be dried up, and then to iron through a dry rag an iron. However, poor-quality manufacture of skins all the same will have an effect - separate details (lapels) under the influence of a moisture can be wrinkled or be blown up by a bubble. One more means - to take a leather product in hands: the skin will heat up, the substitute remains cold.
