So, I've been preparing for my first pit-fire and I was bisqueing my last load of pots before the
pit-fire. I was going to bisque the load to cone 010. With the #10 fresh in my mind, I acidently
fired the load to cone 10(big differance), and I didn't realize that I did so until I noticed my
kiln being extremly hot after 16hrs of fireing and in big letters ERR1(error 1) on my paragon
eletric kiln.
My question is should I have any hopes of these pots being affected by the pit-fire? Or will they
not be affected at all?

I would not even try that. Your clay should be vitrified at ^10 which =
means
that you will almost put "glass" in an uneven fire. So you will loose =
most
of them if not all. Also when it is vitrified all the fluxes are melted =
and
there will be no room for the smoke to penetrate your pots. Sorry for =
your
loss, but this is a perfect time for you to try out other decorating =
methods
outside the kiln.
Do you need sharp trimming tools that will not wear out quickly? Contact =
me
for information.=20

Scott, pit firing is so physically demanding, I wouldn't even bother. Clay
is cheap; make more pots.

Scott -
They will likely crack in the pitfiring, because they have lost most of
their thermal shock resistance. Bisque-fired pots are very porous, and have
very high thermal shock resistance, and thus can withstand the uneven
temperatures of the pit fire. High-fired wares are no longer porous, and
thus generally are far less able to withstand uneven heating and cooling.
You'd be best off firing these wares in some other way.
Good luck -

When I sawdust fired in a barrel pots that had too high a bisque they all
broke.Never happened before or after. Probably were too brittle to take the
shock. They did take up a bit of colour, but not as much as usual.
I`d just try it and see what happens.

Scott, they are extremely unlikely to be affected
in the way you mean. The clay is already vitrified,
and won't pull in carbon or much of anything else.
But - you could stick one in the pitfire and see what
comes out.
