Sometimes when you buy yarn there is no indication on it as to whether it is synthetic or wool. If this is the case or you have bought some wool from an unknown source and are not sure it is as stated, try this sure fire test.
Cut a couple of inches from the yarn and put it in a saucer with a little bleach, make sure the bleach covers the yarn. Leave it for a while I usually leave it for about an hour. If the yarn has melted and disappeared then it is wool, if it is still there then it is synthetic.
