indestructible clay recipe

i need an indestructible clay recipe (or at least one that can resist
extreme thermal shock). i would assume low silica, high alumina would be
in order, and that a refractory brick recipe would be a good one to use.
maybe a spodumene/petalite body would be a good idea? high plasticity is
not essential, but the more plastic the better. does anyone know a good
recipe?

thanks for your help!!

I don't know how extreme you mean, but WSO from laguna is what I use for
raku and it is pretty amazing....I've refired things 3 times, complete with
the hitting them with cold water when there still really hot, and they
haven't broken....

Mike,

It would help if you shared with us what you want to do with the
indestructable clay.

i'm making structures to hold electric heating elements. they will be
heating up very unevenly and quickly, and so far all the pieces that i
have made cracked. i'm hoping to find a clay that won't crack as it is
being heated.
