What Is a Mordant? To be successful at natural dyeing you need to know a bit about mordants and fixatives. Basically, natural dyes will not adhere to natural fibres without the use of a mordant or fixative. Whilst you may initially get a beautiful result from the dyeing, it will soon wash out or fade away!
