How To Test Real Mulberry Silk?

Satin is not Silk. When you buy a “satin silk pillowcase”, it may not be 100% real silk pillowcase but rather a polyester (plastic) satin fabric.

The best way to test for real silk is the burn test. Since ancient time until now, it is still very common practice to bring a lighter to silk market (in Asia). It is foolproof that the merchant cannot hide because if it’s not 100% pure silk (but mixed few small % of polyester) it will burn like “burning plastic” (see explanation in the video).
