Hi Curt: Axner pottery in Orlando, Florida, has a sculpture body
formulated by Nan Smith of University of Florida Ceramic Dept. She
makes life sized figures. I think it is just called the Nan Smith Clay
Body. They also have a raku body that can be used for sculpture,
Sylvia's Raku Body.

Dear Curt,
I make huge chimney pots with a combination of thrown, slabbed and extruded
clay and the bodies I use are straight forward buff and a red terracotta,
both have an addition of 15% grog. I have found that it is not the body that
you really need to worry about but how you stiffen and dry. My pots are up
to 2 foot square and up to 6 feet tall and the way I stop them from cracking
is extremely simple and up to 90% successful. When you have put your piece
together and need to let it stiffen up wrap it up in newspaper, this has the
effect of equalling out the moisture from one part of the structure to
anotherand evening up the stresses, having got iit wrapped then cover the
lot with plastic bin liner bags. Plastic on its own will not work to
transfer the moisture. Leave for a week to ten days (when I try to speed
things up I then get cracks!, but then I am an impatient guy) unwrap and
finnish the pieece and then allow to stiffen further with newspaper drapped
around it. If I have to speed dry the pots then I leave the newspaper on it
while I have my turbulators (big fans) running for several days, take off
the paper when I introduce the heat and you should have no more cracking.
I also place my work on several layers of newspaper and oon a board , so
that in drying the piece can contract on the paper quite easily. This really
does work, and has been for over eleven years now. Newspaper is really
magic.
Happy potting
Marek

At the Appalachian Center for Crafts we have a very versatile body which we
use for bonfire, raku, and for sculpture at all temperatures. It is
extremely refractory, and is not completely vitrified even at cone 11. It
is equal parts goldart, fire clay, ball clay, and grog. For large sculpture
I would use a fairly coarse grog. We use extra-fine grog for bonfire and
raku, and it works great - very few problems with cracking during drying or
firing.
Good luck -
- Vince

Curt,
Since I can tell your in the Mid Michigan area, you should go out
to talk with Mark Chatterly in Williamston. He does life size sculptural
work and may be able to give you some good hints. I know he adds a lot of
grog to his clay. I was lucky enough to have him
as an instructor for a couple of classes I took. Nice guy.
pam, lansing

George Wright makes a clay called 'hair of the dog' it has fiber in it and is an
extremely strong sculptural high fire clay... There is a article in CM last
year...sorry don't remember the issue, that gives Wright's receipt.
As has been said, drying is also important.
Thanks for the newspaper idea... I'll try it.
