Just to let you know, manganese oxide (in powder form) is a glaze ingredient used by potters. I have worked alot with clay and used to use as a colourant on clay sculptures. I would drop an arbitrary amount of powder into water and then dip a sponge into this solution to dab onto fired clay. The material data sheet clearly states that it can be absorbed directly through the skin into the nervous system. This fact has caused some potters to stop using it. I do not have pd but always wonder if using it has put me at risk. Juut as an aside, my mother did have pd and most of her adult life craved liver which of course is high in iron. Is there any correlation to iron-rich diet from organ meets and pd? joan former cg ----- Original Message ----- From: "Arnie Kuzmack" <[log in to unmask]> To: <[log in to unmask]> Sent: Wednesday, June 21, 2006 6:40 AM Subject: Re: Manganese, well water, and PD >>> Ingested manganese is an essential nutrient.
