Trace amounts of metal can be dissolved in solution.Posted by Faery Ring on August 23, 2001 at 23:09:36: In reply to: Perhaps more relevant to fiber arts than skin posted by Catherine Cartwright Jones on August 23, 2001 at 22:16:38: I think that iron can penetrate the skin because it is such a smallmolecule but it is unlikely a lot can penetrate since iron dissolves in water with great difficulty. I don’t know about iron oxide (that’s not iron metal is it?). What about adding some iron filings into the paste to see if it zaps it somehow? Maybe the iron molecule interacts with the hennotannic acids causing it to change color? One could try picking up some iron supplements from the health food store and mixing that into the paste. Hmmmmm time to check out the local health food store.
