I pretty much finished this model (18×24″) today, except for minor surface cleanup.
For those wondering about the clay I use, this is water based raku clay which I find extremely stable and has absolutely no tendency to warp or crack even in very thick slabs and pieces such as I work with.
This is approximately 2-1/2″ thick, 18×24″ moist, when dried it will probably wind up around 17 x 22-1/2″ or a little smaller. I do not as of yet own a kiln, so these are not fired, but are used for master patterns to take silicone molds from.
For the most part I am able to pull the mold and the greenware model almost always stays nearly intact- leaving open the option to fire it later to keep.
This is the first of a planned 3 panel set.
