John:
That actually explains my normal Raku process.
I use a stoneware clay (Laguna Soldate 60), and bisque to cone 06. I then
Raku fire at a rate of 45 to 60 minutes and then pull and reduce for 15 to
30 minutes before quenching in a bucket of water.
I have very good survival rates using this clay and process.
Good Luck!

I've used bisqued stoneware for raku many times. Just fire it the same
way you would regular raku clay. It usually can take the thermal shock
very well.
I've raku fired terra cotta too and had great success. The only
difference I did when doing the terra cotta was to bring up the temp
slowly.

Dear John Olson,
What a pity you have not got a dozen or so of these to experiment
with. Being so restricted I would suggest you just get on with it.
Best regards,
Ivor Lewis.

John, I'm not completely certain that I understand what it is that
you are asking but will try to answer anyway. If you are just refering
to the use of a "stoneware" clay body that has only been bisqued, as in
one that will mature at cone 6,10 etc., and is generally used for
utilitarian purposes then we are on the same frequency.
I use three different clay bodies for my raku pots, depending upon
the size of the piece and the type of glaze that I'm going to use. All
three are stoneware bodies. Two of them are bought, Lagunas WSO (a real
nice white body with teeth), one of my own concoction, and Armadillo
Clay's Buffallo Wallow. I have started bisque firing all three to an 04
rather than an 06. There seems to be a bit more strength in the finished
pieces because of this.
Do not do anything differently in the application of the glaze as
you would with any other type of body that you have been using. The only
area of potential concern is if the "stoneware" body that you have is
not up to the thermal shock that will be inflicted upon it by the raku
process. If there isn't much grog or kyanite in the body you may run
into difficulties. What type of body are you using?
Before you have a go at it with any sort of really important
pots/pieces or any open forms give the body a test spin with a coupla
closed forms and see what happens. Additionally, take few scraps of
Kaowool type blanket and put them on the hot shelfs. Place the pots on
the scraps. This works very well to reduce cracking. One more thing to
keep in mind is that you do not need to set any speed records from
firing to firing. Take it easy when firing up until you get to know your
body. There is no initial need to shoot for fifteen/twenty minute cycles.
Hope this helps

Hi John,
I've found most stoneware clays I've tried out survive a raku firing
okay. The ones with zero grog or sand in them tend to crack more often.
Sometimes they survive and have the best glaze colors, though. Of
course!
My personal favorite raku clay is IMCO Sculpture 412. It's a buff
stoneware so you get fairly white crackle whites, and the survival rate
is well over 90 percent. Plus you can throw it without removing too
much skin from your fingertips. :-)

Hi Laurie,
Well, that's just the "secret trick" if ya wanna have raku with
exquisite crackling....
Those microscopic fragments of finger skin left behind in the clay.
