Ever since using this base glaze in '64 at the University of Oregon, I
would see small patches of yellow to pumpkin color from time to time, while
mostly seeing a liverish red from our C/9 Reduction fires there. It was not
until about ten years ago when I added C/10 Oxidation fires to my routine
that I got the yellow color with regularity. The glaze is on page 82 of Ian
Currie's "Revealing Glazes", available here:
http://ian.currie.to/
The glaze is VERY sensitive to thickness, and needs a clean white surface
to give great color, so porcelainous clays are what I use with it. Perhaps
the color might be lighter with less copper, and someone may want to try
this and report back here.
Happy after my holiday sale, Hank in Eugene

Francine,
Would you mind telling me a little more about your experience with yellow
cerdec stain. I have been looking at a yellow glaze in Mark Burleson's book
which uses stain. It's a cone 10 oxidation glaze so I would expect it to be
using cerdec stains although the recipe doesn't define that...just says
stain. This is the recipe which is shown on a piece by Robert Moore.
Feldspar (G200) 43.0
Silica 25.0
Whiting 18.0
EPK 7.0
Superpax 7.0
Yellow stain 10.0
My experience with cerdec stains has been that they are either spotty
(probably didn't use enough) or kind of flat and dead looking. Anyway, I was
wondering what it is you didn't like about your glaze effect.
I'll be interested in what the group comes up with in response to your
question. Sorry I don't have actual help to offer.
