"You can confirm content by burning a small peice. If it goes to ash, it’s a natural fiber. Fine ash is silk, courser ash would probably be cotton (you’re not likely to mistake one for the other anyway…). If you get a sticky resin or ball of plastic from burning the fabric, it’s obviously a synthetic material."
Of course I knew that about burning versus melting, but no, I would never have thought of actually *doing* that.
What about when it’s a mix? Say, cotton and poly? Can you tell when it’s 65% cotton/35% poly versus 65% poly/35% cotton?
