1. Look closely at the structure of the fabric - if its surface is perfectly smooth, in this case it is not a virtue, and weakness. Perhaps you caught polyester, because real silk usually has small bumps.
2. Pay attention to the color and luster of the fabric. This silk is not completely white, it should be easy to thread creamy shade. Silk has a noble, gentle luster, but the sun shimmers playing shades. Glitter artificial tissue poorer, white glow.
3. Silk natural origin acquires body temperature, so cold it warms, and the heat does not overheat. If you will press the fabric to the hand and feel the cool, artificial fabric. Crumple the fabric into a ball - it should not remain clear wrinkles.
4. Gently pull a few strands of fabric and set fire to them. Silk lit, highlighting the sharp smell of burnt hair or feathers. Thread fold into charred balls and turn into ashes, if you rub them with your fingers. Isskusstvenny silk when burning will melt, making the smell of burning plastic or burning cellulose.
5. Note that the silk will not be sold in vacuum-packed. Otherwise it "choke" and begin to exude the smell of mold.
6. Quality silk can be determined by trying to break it. Damage the silk so it is practically impossible: its threads have strength steel wire, but the artificial tissue can not survive.
7. Please note that the price of silk can not be low. If a trader can easily amenable to persuasion to reduce product cost twice as likely, you are dealing with a fake.
8. There is another way to check the silk. Put it in a 7-10% solution of alkali and heat. Silk fabric is of natural origin (yarn for her produce silkworms), so will dissolve without a trace. Artificial tissue withstand this test. Despite the accuracy of the method, apply it in a store or on the market, unfortunately, will not succeed - if only to scare the seller does not want to disclose the truth about the origin of the tissue.
