I am reading this thread just after reading Mel's post about "getting off
the bus" and I am wondering why we generally have a tendency to baby or
pamper clay. Of course the firing cycle for bisque depends on the kiln, th=
e
volume and the dampness of the work when the firing is started. For the
past several years I have been bisque firing in a gas kiln, the Sk----
electric kiln we have has not worked well in more years than I can remember=
.
I tend to candle the work overnight with just the lighter tubes on. With
the damper nearly closed the kiln is above 300 F when I get back to school
in the morning. I tend to bisque low - between 1650 and 1750 F, once the
temp has reached 1050-1100 F I give the kiln full throttle and reach the
target temp quickly. Usually I get from 300 F around 8:30 am to 1750 by 3
pm. Unload the next morning and start glazing. I should mention, all of
this is in a 14 cf downdraft from Olympic kilns, a wonderful machine.

For my last 7 firings I've averaged 6 hours and 6 minutes for a ^08 bisque.=
Usually that means an hour on low, an hour on medium, and then zoom! Up =
to bisque temp.

Hi Randy,
I use Seattle Pottery Supply's CKK6 which is listed in their catalogue as a
Cone 4-6 porcelain.
At first I bisqued to Cone 06 but found that rims on pots weren't absorbing
enough glaze.
So I switched to Cone 07 bisque and have solved the problem. (I glaze fire
to Cone 5 with a
slow cool-down, and use Cone 6 glazes).

Randy: It is humid here. I load the kiln and candle the bottom for a few
hours. I turn turn top and bottom up to LOW settings gradually and I can se=
e
steam and smell the "water smoking" when that is done I start cranking it u=
p
through the middle ranges. 06 is the best but sometimes I use 08 or 010,
depends on the clay and glaze combinations. Quartz inversion happens in the
dull red zone so I still don't get to excited until we have a cherry red,
then I go ahead and drop the cone ending up on HI. From beginning to end 12
hours. If I candle decently overnight I am more bold and probably fire it
off in as little as 6 hours, not including candle time.h a n s e n
