This is probably the worst time to ask a question with "everyone" heading
off to Las Vegas. (Have a good time!!)
But, is it possible, advisable to use rutile to make a yellow gold stain for
overglazing with? I have been using it at Cone 6 with the Plainsman
overglaze medium (about 2 or 3 of it to 1 of rutile). It behaves about
half the time, but an accidentally too-thick application goes rough.
Refiring never seems to help.
Would mixing it directly with a clear glaze be a better idea? Or GB or a frit?
Thanks,
Autumn Downey

We are phasing out the use of rutile in a lot of our products and are not
advising its use to our customers who want a consistant colour over time.
It has proved to be a very inconsistant material with variations in
concentration, colour production etc
For a constant yellow i would suggest a glaze stain of your choosing at a ratio
of 10% dry weight in a clear glaze. If the stain is of a good concentration this
should give you an opaque glaze.
You would be surprised how many commercial glaze manufacturers use this method.
If you want it to keep over time. Add a bacteriacide to prevent it 'going off',
and and an organic polymer to suspend it.
