process of testing cone 6 glazes

Paula Reynolds on wed 13 jan 10


I have mixed up some Cone 6 glazes from MC6G and from articles in Clay Time=
s
and the tomato red from John Post's website. I did not get the results I
hoped for even though I used the recommended slow cooling firing schedule.
What I need help understanding is what is the next logical step in testing?
Do I just refire the ugly pots and change the firing schedule? Do I thin th=
e
glaze and dip more pieces and refire using the previous firing schedule? I
would appreciate hearing what process some of you use when you don't get th=
e
results you wanted.

Unless the glaze was too thin to begin with , you don't need more.
Make a note of the clay bodies used in the examples compared to what you =

are using.
The holdong around 1850 on the cool down does wonders for some iron =3D
reds.
I held it for 15 minutes to 1/2 an hour and got different results.

Hi Paula,

Application thickness may be the problem.

Perhaps doing some tests varying the thickness of the glazes will
help. If you scratch through the glaze after applying it you can see
how thick it is.

If you need more let me know.
