Hi,
I'm preparing some pots for my first pit firing that I will be contributing
pots for. It was suggested that I fire to cone 010 because it is somehow
most condusive for burnished surfaces?? But I also want to bisque (this is
all low fire clay) other pots for other surface treatments that will not be
for the pit. Is 05 allright for all or is this too general a question (my
other experiment calls for 05/06).
Thanks from beginners mind,
Centa

Centa,
The lower you bisque your pieces, the more smoke they will absorb. I
also burnish and then bisque to cone 06. The shine remains and a lovely
smoke pattern results. I have not tried a higher bisque.

Hi Centa,
a brief response from another beginner... I've been primitive firing all
bisque has been ot ^012...for the reason you stated. I would imagine the
less porous the clay's surface the less carbon it would be able to absorb !?
If you want a good pit result it may be better not to fire at the higher
temp.. We're getting ready for a pit fire and I'll raise your question to the
other potters.
Good luck

Hi centa,
I stop all my burnished ware firings at 012. Some will survive at higher
temperatures, but generally the burnish begins to lose it shine quickly at
higher temperatures. You will also get better carbon penetration in your
pit fire with a lower temperature bisque, 05 is too hot for that. I use 018
to 012 for all of that kind of work.
Good luck,

Yes, you can pit fire pots bisqued at cone 05 or 06. You need to do
some experimenting, since different clay bodies and different firing
techniques produce a wide range of results.
I fire a cone 9/10 white stoneware in the "pit",and bisque to cone 06.
Lower bisque, for me, absorbs so much smoke that I get mostly a smudgy
looking darker pot...whereas, cone 06 bisque gets very black where in
the sawdust, and wonderfully colored where it sticks above the sawdust.
But...that's what works for me....Keep trying new things, and you will
find what produces the results YOU are looking for.
Good luck

we bisque at 00.1 before pit firing...I didn't realise that you could get
darker pots by bisquing (sp :) ) higher...ours turn out really black in some
spots with reds and oranges
