Does this hold true for raku? It'd be nice if I only had to buy 1 kiln
instead of 2. Of course the electric kiln is the one the neighbors probably
wouldn't object to ;-)

Simona,
Yes, you can single fire raku, but presently (until someone develops a
claybody capable of maturing properly without damaging) it would not be time
efficient to fire this way. You can bisque in your raku kiln--by staking
properly, putting pots in each other, touching each other, you can get quit
a few pots in any bisque firing--more than if you were doing a glaze
firing--thus the reason, in the case of raku, to bique, and then fire (until
a body is produced such as I mentioned. I have some raku kilns I designed
I've been working with and I have bisque out in the field while doing a
residency. Worked just fine.
Thank you.

Only if you can heat it up as slowly as a bisque
firing. That's true for any one-shot firing,
regardless of the final temperature, atmosphere
or process. If you can, then yes, you can skip
the bisque firing. (It does mean that you can't
do a half-dozen raku firings in one day.) You'd
have to ease the heat up into the red-heat range,
THEN you can kick it up faster until your glazes
mature. (Not all that much further, for raku.)
Most specialty raku kilns do not allow for
fine control of the heat, so getting through
the lower temperatures with greenware will
require a bit of practice, or the use of a
more conventional kiln. And you'll be limited,
both by the longer firing time and the need
to let the kiln cool before reloading, to
perhaps only one firing a day. But it should
work.

Simona, Just last night I was looking though my copy of Creative Pottery, a
step by step guide and showcase. One of the featured artists is Jim Connell
who uses his electric kiln for firing Raku. From what I understand, he
applies glaze (receipe in book) to greenware and fires to ^08. After pots
cool he reaplies glaze to parts of the pot where it is too thin etc. He
then fires to ^08 again and pulls the pot and finishes the Raku process. I
tried to find some pictures of his work on the web, but didn't have any
luck. Possibly I can figure out how to scan a picture of the book and email
it to you. (POSSIBLY)
