The iron does not touch the product, only the steam needs to be brought closer. While there are many ways to understand that silk fabric is real, the easiest is to burn a small piece of fabric. Real silk turns into ash after being burned. A hair burn-like scent emerges. It can be compared to burning a dried leaf. Satin and polyester, which are the two most used imitator fabrics instead of silk, do not turn into ashes, plastic small bubbles form in the place where it is burned, leaving a plastic scent.
