Hello everyone:
Would anyone out there care to recommend to me a *very* white commercial clay
that would hold up under Raku firings?

Have you experimented with your regular clay? I've used a wide
variety of clays for raku -- cone 6 and 10 stonewares, cone 5 and 10
porcelain, as well as 2 different raku bodies. None of the clays
withstood thermal shock any better than the others, as far as I
could tell.
I did have problems with the bottom of slab built pieces cracking
off. Preheating the piece by putting them near the burner didn't make a
difference. What finally worked was to put a room temperature brick
on the kiln shelf, then the piece on the brick.
I also only spray the pots lightly with water when I take them
out of the trash can (reduction chamber). Just lightly enough to
stop the reoxidation. I then let them air cool.
I've lost a few pots by having them tip over onto a pebble. They
seem to be very much more fragile when hot.
Guess I've rambled enough. I'm curious if other people have found
an advantage to using one of the raku bodies.

AMACO makes a white raku clay. You can purchase it through The Brickyard in
Indianapolis, IN (800)677-3289. AMACO may have a local distributor closer to
you (317)244-6871. We've found the body to be a little short (they add a lot
of grog). You may need to wet the clay a bit and wedge it thoroughly to get
it to a useable consistency depending on what you'll be doing with it.

Here on the west coast a lot of potters use a white cone 10 body called B-mix
for rakuing. It throws and fires well in Raku.

Trinity Ceramics, in Dallas, has a white stoneware that works great with
the raku process.

thanks to everyone who so kindly responded to my querry regarding types of
clay to use for raku.
the concensus seems to be that any clay with some grog/sand will work. yet,
people specifically mentioned mid and high fire clay. so i am wondering why
low fire clay was not mentioned, as raku is a low fire process...
thanks, again.

I have used earthenware in raku and it seems to work. Red clay has a
tendency to crack, however very cleanly so its easy to reassemble. White
earthenware as well. Neither clay stands up well to the shock of water
after the reduction bucket. Hope this helps

The short answer is Yes. I have Raku-ed ^6 clay (that actually had very
little grog) and didn't have any problem. It all depends on how fast you
fire and how you reduce the piece and how the piece is shaped.

jim,
i use 'raku' clay from 'continental clay' in minneapolis.
it is a cone 10 stoneware with grog and perfect for raku firings as well.
i like to use it, so i dont have to decide how i will fire the piece before
it is finished.
this way the piece can be raku fired, sometimes pitfired, or electric ^6,
or reduction to ^10... glazed or not...
i fired it in wood, soda, salt and anagama too.
hope this helps,
marta

as many have noted, a ^6 stoneware with grog (or even
something finer) should be fine. I wanted to add that
i took a ^6 porcelain bottle (standard's S213
Porcelain Clay without any grog added) out of a raku
can this summer, dunked it in water completely
incorrectly, and it did not break.
This was 5 pound, 13 inch high, 5 inch wide, with an
opening no longer wide enough for the potter's pinky.
First i dunked it, let go, it popped to the top.
then i held it under for 20 seconds, then i let the
mouth out of the water for a bit until the inside
filled with water.
Granted, we let the reduction can's get a little
cooler than I am used to but this goes against
everything i have learned about raku.
at the end of the day - you should feel safe with ^6
stoneware with grog. But of course - test, test,
test.
do a small test kiln with different clays (if you have
then) with and without grog.
we actually did use a test kiln and then carry it
outside and reduce there.
after testing the clay's you will have all the
definiative answers you could possibly need.

Hi Jim,
I use Standard's 181 white stoneware or a ^6 porcelain for small to medium
sized pieces - especially those I terra sig. I find that unevenly thrown
pieces or pieces larger than about 10 inches (in any dimension) crack or
break. For larger pieces I use Campbell's Raku clay - very groggy, little to
no breakage. I also use a reddish stoneware from Standard (235??) that seems
to work well.

Having never done Raku and after searching the ClayArt archives, can I raku
bisqued cone 8-10 porcelain? I'm just doing a (one time) quickie morning
workshop and I don't own any low fire clay. I just want to have the piece
survive. I read somewhere that you could use any clay, just wedge dirt into
it. This seems rather treacherous and I'm not sure it would work with
porcelain. Tips on throwing thickness and shapes would be appreciated.
Thanks, Ronda Shulenburg
