I need your help- There was mention here on Clayart of an article about the
toxic effects of Manganese, reported to have been in an early 1995 issue of
Contact magazine. I have looked in their archives , as available on the
net, and have not found any such reference. I have also sent a direct
e-mail message to the Magazine, with no answer at all.
Since I am in the grip of a malady for which we dont know the cause
(Peripheral Neuropathy) but for which heavy metal poisoning is a suspect, I
need this reference (or any other, specific, reference) If any of you have
a copy of this article, or can point me to it, I would be ever grateful.
As a matter of interest, when I was tested for "heavy metals", I was
surprised to find that neither Barium or Manganese was normally in the list
of the metals looked for. I intend to follow this up, but a discussion of
effects would help.
To those of you who may remember that I was anticipating surgery- That has
been postponed because of a Urinary tract infection, which has now been
cleared- It looks like I may make the scene the week before Christmas.
Bill- waiting it out on Persimmon Hill.

Dear fellow sufferer, PN? Me too. So far it only affects my large toes to
any extent. According to various medical advisories: A- it is the result
of poor circulation coupled with 35yrs of Diabetes. B- I froze my feet
very early on,(about 65yrs ago) and the poor circulation is the result.
C-It may be Candida. Hang in there,child. don morrill

Bill A: Here, for you (& Clayart) is the reference you asked for. The
title: "Potters Manganese Toxicity" by Elke Blodgett who became sick from
her raku firings. Ms Blodgett discusses her experiences and her ailment
quite candidly, and includes a transcript of a conversation with her
physician about her sickness. Ms Blodgett's in-depth article appeared in
the Autumn 1995 issue of Contact magazine.
This article is a must-read for all potters working openly with
manganese compounds, especially those using them in raku firings.
On the basis of a limited discourse with Ms Blodgett, I believe I
am correct when I suggest that she is willing to communicate further on
this topic. She is on the Clayart list and her email address is:
eiblodge@freenet.edmonton.ab.ca
I will also forward this post to her directly.

Bill, you need to contact Elke. She is probably still online. She wrote
the article about this. If you don't have her address in your address
book it is: eiblodge@freenet.edmonton.ab.ca.

Hi Bill:
You need to contact Monona Rossdol via E-Mail at
75054.2542CompuServe.com
She is a specialist in ceramic toxicology and will be able to answer most all
of the questions you may have on the use of manganese and it's physiological
effects on the potter.
Best of luck and do be careful. When in doubt stay away from suspected
toxins until proven otherwise.

Bill:
Robert Pipenburg's new book "Spirit of Clay" of some such has a chapter in
which he talks about the toxic effects of various (no almost all) the
chemicals we use and he makes a comment almost in passing the manganese is
very toxic. I use it and am a bit curious about it, too.
Any wisdom on this folks.

Dear Bob and all others out there: STOP being just a bit curious, esp.
about toxic glaze chemicals such as manganese. Contact Monona Rossol
and get an off-print of my article on how one potter almost did not
make it because she was not curious enough early enough.

Hey Don---just to let you know-- periperhal neuropathy is very common
for people with diabetes, I just did a medical search for a friend in the
MEDLINE database. What Bill is suffering from is different, and hopefully
reversable if he stays off the manganese for a while...maybe forever!

"I need your help- There was mention here on Clayart of an article about the
toxic effects of Manganese, reported to have been in an early 1995 issue of
Contact magazine."
Bill;
There is an extensive list of chemicals and their
hazards/toxicity/identification at:
gopher://ecosys.drdr.virginia.edu/11/library/gen/toxics. I found this while
researching the ceramics web
glazebase at SDSU (http://apple.sdsu.edu/ceramicsweb/glazedatabase.html).
Good luck on resolving your health problems. I have been told by an alternative
medical practitioner that
supplements of Chlorella or Spirulina are helpful in ridding the body of heavy
metals. Certainly can't hurt to try.
It would be a good idea for all of us to become more aware of the materials we
are handling. Those glazes look so benign sitting there in their buckets. We
tend to forget the hazards they can pose to our health if not handled
correctly.
Stay healthy!

Bill - Good grief - hang in there. Richard Zakin had some kind of metal
poisoning & wrote about this in a recent article of Clay Times. To
locate this issue, suggest you phone Rick Berman at Berman Gallery
in Atlanta. Good luck. Karen Gringhuis

Hi Bill,
I will look up which issue of Contact had the article about manganese and
get back to you.It was before we took over the magazine so it is not at my
finger tips.If you have a fax let me know or call me at 1-800-304-6185.

Tom,
Do you know why manganese would be more toxic in raku than in other firings?
Wendy from Bainbridge Island WA
ret on sat 14 dec 96
Hello Wendy. Re your question to Tom: One of the questions I asked of my
Occuational Health doctor was: is manganese in any form toxic or is
exposure to vapors worse than inhaling dust, for example? His answer:
Vapor appears to be worse than dust. Manganese content in dust, in clay
and that sort of thing is not necessarily bio-available; so, although it
is true that many clays and many other minerals contain manganese, that
manganese is not necessarily available for
distribution in the body once it is inhaled. As a pratical matter, the
biggest problem is the fumes."
Other physicians insist that any form of exposure is just as dangerous,
but
doing raku firing you inhale astronomical amounts in vapor form,(very high
concentraion all at once) usually
along with copper, and get a good dose of metal fume fever along with
the neurotoxicity caused by the manganese.
I, personally, would be quite suspicious of the beautiful "pewter" glaze
and would not hang around in a kiln room when it is being fired.
Or use it on functional ware.
Again, contact Monona Rossol 75054.2542@compuserve.com to get an
offprint of the whole interview, etc.
