HOW TO DETERMINE SILK QUALITY
Do a Touch test. This is a quick spot test that one can do especially before buying a silk liner. The idea is to rub the silk with your hands. If you feel warmth on rubbing it, go buy it! It’s real. With artificial or synthetic silk, it is impossible to experience warmth on rubbing.
Perform a Wedding Ring Test. If the silk that you are planning to buy is not very heavy, this test is perfect! Genuine silk of lower ply can be easily threaded and pulled through a wedding ring because silk is naturally flexible and smooth.
Silk is especially known for its lustre. The lustre is usually because of the combination of threads which gives a particular sheen to the material. The color on the surface appears to change as the angle of the light changes.
Do a Burn Test. The bunch of Silk burn slowly with faint glow. Firstly, it will curl into a ball with a similar smell of burning human hair or bird hair. Then, after burning into the dark brown globular, once you touch the globular,it will be broken into powder. Finally, when leaving the flame, it stops burning immediately. The burning silk should smell like burning hair.
