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

Beth, I sent this into Clayart last night but for some reason, if I use my
address book, my emails do not get posted even though it is the exact same
address as when I hit 'reply'. Weird.
Here is what I sent in:
I have this in my glaze file and checked the website but have never tested
it. It is still there. Please go to:
http://www.jqjacobs.net/art/glazes2.html#noxema
I think this may be what you are looking for.
