Yes.
The thing that defines raku is pulling it out red-hot.
Many people, however, also take the work up
almost as quickly, usually reaching red heat in less
than an hour. This would kill most greenware. If you
are willing to fire your raku just as slowly as a normal
bisque, however (and if your glazes are greenware-
compatible), it will be fine.

Just a quick question for the Gurus...
Is it possible to single-fire Raku ware, since the bisque and glaze =
temps are pretty much the same?
Using Laguna Raku Industrial BTW.

Thanks.

As long as you heat the work with the kiln, no reloads.

Cathi:

While all things are permitted to you, not all things are beneficial.
The raku firing at least in North America is often a quick affair with
the piece going from warm to done in at little as 15 to 30 minutes. If
you tried that with green ware you would have a steam blow out for
sure. Still, you may want to try it if you can overcome the problems
associated with rapid firing of greenware.

Most raku artists will do a practically slow bisque so that when they
go to glaze fire and post reduce they can do so with rapidity. You
should say this every time someone pulls a pot out of your raku kiln:
"Do so with rapidity." It makes for a great motivator. Maybe even
engrave it on the raku tongues. That would be a nice touch.

To recap -- 1) be humming that great Johnny Rivers song, "Slow
Bisquing" while you load your kiln the first time. Don't rush it, this
is special. 2) don't forget to effect an English accent when you tell
the pot pullers, "Remove to the reduction canisters and do so with
rapidity." A French accent is also appropriate if you can pull it off.

and lastly...

Keep the raku fires burning,

Taylor, Snail, Lee et al...thanks!
You all pretty much confirmed what I thought.
I tend to heat my raku pieces really slowly, over 2 or 3 hours as I do not
like shock. It works for me and I don't have much breakage.

Taylor, along with your mantras, I also reccomend looping "Sukiyaki" on an
MP3 and turning it up to 11 - works for me ;)

Anyway, I have spent this last week (now that we have passed Final House
Inspection and can take a break) setting up my kilns at the studio and while
my ^10 kiln is still awaiting the propane guy, I built myself a 55 gallon
drum Raku kiln (weed-burner fueled) that can handle bisquing too.

Filled it for the first time yesterday and was noodling about why I was
doing a bisque only to turn around and glaze and fire again for Raku (this
load has some ^10 pieces in it, so I could not do a single fire this time).
So I am anxious to try this. I usually bisque over about 7 hours, to about
1,000 cent, so at the end of that I can just open up that door and pop those
lil guys into a reduction :)

If anyone wants to see my progress and raky kiln, here's a link to pics BTW:

Now, about rice hulls - can I use them in a Raku reduction?
I have 1/2 a bale here looking for a purpose. Used the other 1/2 to stuff
burlap coffee bean sacks for dog beds.

Thanks everyone...I'm off to see what the kiln has given me!
