How do you know whether your purchased silk sheets are real or not? Usually, you will get a small piece of silk when you buy them.
Some people may doubt what it is used for. Actually, it is used to let you know the silk you get is real or not blended. You can take this small piece of mulberry silk sheets and do the burns test on it. Notice how it burns and the ash that produced. The edges where the burn takes place should not fray but stay very straight.
As for the ash produced by a piece of silk bedspreads, it should be very soft and light. Please be careful when doing this.
