How To Identify Real Silk？
The burn test：This isn’t a method that we’d really recommend unless you want to chance completely destroying your silk fabric, but the accuracy of the results can’t really be beaten.
Flames:Burning genuine silk produces a smell very similar to that of burning human hair. The flame is close to invisible when burning the edge of the real silk fabric. Very soon after the flame source is taken away from the fabric, the silk will self-extinguish.
Ashes:The ash from burning is black, crispy and turns to powder easily when grinded.
Flames:Most fake silk are in fact petroleum based polyester products. When burned, these materials tend to combust rapidly in intense flames, and give a smell of burning plastic.
Ashes:The ash of fake silk tend to be sticky, twisted, and difficult to break apart.
