Dear Fellow Clay Arters,
Is there any such thing as a yellow for cone 10 reduction stoneware that
does not contain barium?
I love firing and the clay I use, but it would sure be nice to be able
to get yellow.
Thanks,

Dear Jean;
Hank's Copper Yellow is pretty nice on porcelain, or white
stoneware bodies at C/10 in Oxidation. Needs to be fired in a fuel kiln
though to get a really clean atmosphere. You can find the recipe in Ian
Currie's book, "Revealing Glazes", on page 82.
Regards, Hank

Hank,
Try adding 10% of a tin vanadium yellow stain to your favorite glaze. It
willnot burn out at cone 10 reduction and give you the color you are looking
for. Mia in snowy ABQ

This question and two answers appeared on ClayArt less than a week ago and
some may unwittingly put these two suggestions together - not a good idea.
Vanadium is not benign - in fact that much in an already unstable glaze
where it can come in contact with food may be a very bad idea.
Hanks yellow is a cone 10 matte oxidation glaze - it also contains zinc
oxide which may reduce out if fired in reduction. It also is probably not a
stable glaze and may also craze on some bodies.
Keep in mind as well - one way to make an otherwise stable glaze unstable
is to load it up with colouring oxides.
If you are going to use vanadium you would do well to find out what are the
problems with breathing the dust and ingesting it.
