Dear Kurt;
From where I am with internet explorer the archives at
http://www.pottors.org does work but I could not get
through the other way which I like better and that is
http://www.lsv.ceramics.org. Were you able to go
through this way?
Thank you for you help

Hi Ron,
Years back a potter at a craft show in Northern Virginia had mugs, etc in a beautiful blue glaze - told me that it was your receipe - something like a noxema blue ( the facial cleanser jar color) - is this cobalt blue and would you be so kind as to share the receipe?
Thanks!

The problem remains - how do those with limited information - those
starting out in clay for instance - know if the information being refered
to is complete and/or misleading?
The value of answering questions on the list is - false or misleading
information can be corrected.
I have no problem with using the archives but - sending a beginner off
without keeping them company seems rash to me.
If you do go there and point them - why not post the answer to the list as well?

Hi Beth,
I have never used such a glaze - I do work on glazes for many potters -
most times I never see them. I also don't keep copies of most of them so it
may be one of those.
I wonder if it is one of our glazes from our book? There are four blues on
page 100 and one looks like it might be noxema looking.
Did you get the cone it was fired at - I fire at cone 10 reduction.

Dear Beth,
This is a glaze called Noxema Blue, from the archives. It adds up to 66.l7
gr. and I have not idea about it.
NOXEMA BLUE Cone 4-6
Custer Feldspar 38.1
Dolomite 10.0
EPK 9.6
Silica 9.5
Gerstley Borate 9.5
ADD
Zinc Oxide 9.4
Cobalt Carb 3.5
However, this type of blue, sometimes called Medicine Chest Blue (as were
many of the bottles that color at a time prior to more plastic like now,
is easily achieved at cone 6, by using a clear base and coloring it with
Cobalt or Cobalt and an opacifier like Zinc.
For example, a 20 x 5 base,
20 Frit 3134
20 EPK
20 Silica
20 Custer
20 Wollastonite
ADD
10 Zinc
3 Cobalt Carb.
will yield a dark, shiny, semi-transluscent blue.
My next idea for testing is take 20 x 5 recipes and trade the EPK and Ball
Clays in them, and test them with different fluxes. In the few tests I
have, the difference of the flux used and the amount of iron in the Ball
Clay, or lack of it in EPK, yields very different color responses.
I think your search for this dark blue will be easily found with a few
tests of coloring your usual clear glossy glaze. Try Tin and Zircopax, in
combination of Cobalt as well. Different opacifiers yield different
grades of clarity and brightness in the blue color.
Best regards from Alisa in Denmark

Lists are all about discussion. It be ridiculous not to talk
about questions here. But, it is good to give folks resource
materials to help them better articulate what they want to ask
questions about. Reference books, magazine articles and the archives
are all tools that work together. They can help folks make judgments
about the advice we are given.
An informed patient is no threat to the doctor. They are
the doctor's best assistant.

Hi Alisa...I find your posts always intriguing, particularly this cobalt one.
I had a recent request for a cobalt blue mixing bowl and I used my trusty old
Midnight, the glaze that predates the recipe with the same name in M^6G, but
I fired it in Ron and John's slow cool mode. A totally different and to
me,unacceptable look for this glaze. I would like to add to your observations of
material differences, FIRING differences. They also can create amazing
variables with the same glaze.
Lori Pierce in Orange Park, Florida Cool enough this morning that I am
wearing a long sleeved jersey, jeans and real shoes! A good day to clean kiln
shelves. Any comments on Axner's highly touted and pricey, new kiln wash? Is it
really ITC by another name? Or an "act alike"?
sacredclay on wed 25 oct 06
From the book, "Glazes^6" by Micheal Bailey, on page 30, I used the
T13 recipe plus 3%CoO. It produced the colors that you mentioned.
However, I did find a problem where the glaze settled and I used
someepsom salt which changed the color to less brilliant blue. I
named the glaze Vanderbilt Blue, after having toured the Biltmore
Estate in Asheville. the settling may have been due to the minerals
released in the pipes due to the heavy constructions that was going
on about the buildings that month. It's gorgeous.
Kona-4----43
EPK-------5
Bentonite-2
whiting---22.5
ZnO-------6
silica----21.5
ADD
Cobalt Oxide-3
good luck! From Kathryn In NC where it's finally fall-like and
breezy and I get to wear a pullover.
