Sarah, if you like Kemp's 17, have you tried low firing it after the glaze
firing? Try it for a pleasant surprise especially on an open bowl.

Thanks for the tip, Lori. For those of you who are following this, I heard
about this from Lana Wilson in a workshop of hers. Also read it in Greg
Daly's book, Glazes and Glazing Techniques. I have refired all my
oxidation mid-range glazes at bisque temps just to see what happened. I've
found that it helps to bring out the red in certain iron saturate
glazes. Also, for those of you who have not given up entirely on the
infamous Floating Blue, you'll get an interesting translucent minty green
in a cone 06 re-firing.
I've only done this on pieces that are not intended for use with food or
drink as I'm not sure if the might make an otherwise stable glaze
unstable. Perhaps, Ron, John Hesselberth, Paul Lewing, or any other of the
wonderful glaze gurus will elaborate further on this?

Unless you get an ugly green-ish khaki color, which was what I got.

Greg,
I've tried refiring to cone 06 only a few times, and didn't notice that
it did much. And that was for iron reds, which is mostly what I've
heard of it benefitting. I wouldn't expect it to change a chrome/tin
pink, but then I wouldn't have predicted that it would change Floating
Blue either. Although that's such a wierd glaze that nothing it does
surprises me. As to stability or food safety, again, I can't see how a
glaze would change on refiring. Nothing is added or taken away. I
think the effect we're seeing here is that the first firing essentially
makes a frit of the glaze, and so it's a little easier to melt it the
second time.
Paul Lewing, not feeling like one of the "wonderful glaze gurus" on this
one.
