I'm trying to determin if a capote I just acquired is made from a 100 pct wool blanket or a wool/nylon. No label, but has 4 point marks, and may be from a Witney point blanket. I remember reading once that you could burn a small sample of fabric and tell from the ash. Anybody know what ash from wool looks like? I tried a bit just about the size of a pea, got a black ash that crumbles with no hard lumps like I'd expect if I'd burned something with nylon. Thanks, SCL
