I am involved in my very first "art show" next
Saturday. It's in the next very small town over, and
I'll be the only potter-wanna-be, so it's really no
big deal, but, I'm very nervous.
I need to bisque one more load, plus at least two
glaze loads between now and then, so my time is
running short. But here is my problem....
I bisqued a load yesterday.... the timer went off (I
had it set for plenty of time, I thought) but the 03
cone did not bend, nor did the kiln setter fall. The
pieces are considerably lighter in color than usual.
Should I rebisque, to cone 03, or should I glaze and
hope for the best?

Ok. If you can glaze one or so pieces of the misfired ware, put it in the
GLAZE kiln and see what happens. Why? Because the pots may have fired
quite enough to be well bisqued, even if they did not reach c.03. I bisque
only to c.06 and have had no trouble with my glazes. Which of course may be
different from yours.
I am assuming that your ware underfired. So it will be MORE absorbent or
may be more absorbent than if fired higher. You may have to adjust the
fluidity of the glaze as you apply it, or wet the bisque a bit more.
The one "problem" I can imagine might be that some stuff that burns out at
the c.o3 bisquing is not burned out yet. Look for pinholes in the test
pieces. But I do not think that will happen.
Bonne chance! Good luck!
PS. This is NOT a rule. But it can help. Wearing your safety goggles and
work gloves break the cone that did not fall. You probably will need a
hammer. See how vitrified it actually got.

Darla,
If it were me I would rebisque.. just before a show is not the best time to
experiment with new ways of doing things. Your glazes may be just fine , and
tolerant of the different bisque temp and consequent different application,
but they also may not be and with no time to spare you don't want to find
that out.
Linda,
in Toronto where I have definitely taken risks right before a show ( we
probably all do it)

If the ware is bisqued to a lower temperature,
it will absorb more glaze. So, if you don't
refire, try thinning your glaze slightly to
keep the layer closer to the right thickness.
It may take some trial and error. Do you have
any of your ^03-bisqued stuff still unglazed?
Glaze some, and use the 'normal' thickness of
the glaze coat on those as a guide for getting
the right thickness on the lower-temp ones.
If you do re-bisque, babysit the kiln instead
of using the timer, until you can check for
bad elements.
