My professor used to use some RIO she called Iron precipitate. It was
supposed to be better for glazes. It was a much brighter red than ordinary
iorn oxide, but I don't know where it came from.

Did I read somewhere about a special RIO other than Spanish that is better
for glazes? Does anyone know where I could purchase some?

Thanks
Carolyn

Don't know about "special". It will depend on what you're looking for in
your glaze.
Seattle Pottery has a number of different RIO types/grades.
Though not using it for glazes, I just bought some pigment grade 98% for
another project.
Call to see what might work for you.

Where did this professor teach that used the iron percipitate? Might be a
clue as to source. Lori Pierce in New Port Richey Fl.

Ginny Marsh in Louisville, KY. I do remember seeing it once in a catalog,
but I don't remember when.

Dear Carolyn

My supplier (Potclays - Stoke on trent) used to buy spanish iron but no
longer get it . I am told by Harry Frazer that the company is looking into
getting it again.

I have bought some lab quality stuff to test all my irons against when I
have the time.

As usual I have managed to embarrass myself - My wife did a test that
came out a brilliant red. She told me it was made from the iron she got out
of an old bag . So I phoned Potclays to see which iron it was, and got the
big 'cheese' himself (Mr Frazer). We discussed the various merits of red
iron professional to professional. I reckoned he was well impressed with me.

When I did the test again it turned out she used a red stain and I had to
do the groveling explanations to Harry Frazer myself (email - I couldn't
face the phone) .

Another 'goof' - I have a long list of embarrassing moments with potters
of influence and repute.
