Could be, could very well be. I looked to see where the book was published and it was published in GB. (is the UK the same as Great Britian?) Perhaps the dry form of bluing is often used in England. I have only seen it in liquid form in bottles. Mrs Stewarts bluing was always liquid in a bottle. Hmmmm.
