There was a comment about using Lizella clay to cone 6 and/or for
handbuilding. I'd like to add that Lizella is a very useful clay for
handbuilding fired to around 04 (you can take it higher if you want).
In my program at Augusta State University, we use 75% dry Lizella, 10%
Hawthorn Bond fireclay, and 15% OM4 ball clay. No grog is necessary -
you can build large and thick if you want to. The fired color is peach
(at 04). Even beginners rarely lose their pieces. For the person who
feels that terra cotta can be too dark with clear glaze on it, this
recipe does not have that problem.
For a super raku body for throwing that can take quite a beating, use
75% Lizella and 25% ball clay. This body should go to cone 6 in
oxidation, but cone 9-10 reduction is excessive due to the level of
iron. This recipe is also good for large sculptural pieces that are
made with thrown parts.
I'm enthusiastic about Lizella clay bodies. I find they are tougher and
more dependable than Redart clay bodies. Of course, it depends on what
you are looking for. Redart makes silken-textured, deep red clay
bodies, while Lizella is relatively unprocessed with coarse particles
and a lighter color.
In Georgia, we like Lizella because it's mined here. For people in
other parts of the country, you might want to investigate whether
there's a local (or regional) iron-bearing clay that you could
experiment with. If you can obtain a local clay, it will probably come
at a relatively low price.

I'm a Lizella fan - big time - while I lived in TN and had easy access to
it. A friend of mine adds grog and makes wonderful tiles, tile tables,
birdbaths that are virtually indestructible and can be left out in TV
winters (which are mild).
