Cathi I think it sounds more like a clay problem than a firing one. The =3D
very
lumpy clay sounds like it is not blended well and unless you are putting =
=3D
it
through a pug mill or wedging the heck out of it, I would toss it. =3D
Sounds
like the majority of the pots that cracked were slab made of this clay =3D
from
what you say below....Liz Gowen

I am currently using 2 clay bodies - Quyle Kilns' Sierra Gold (high =3D
iron,
^6-10 clay body local to me) and Laguna's 1/2 and 1/2, which is 1/2 =3D
white
stoneware and 1/2 porcelain. I'm not happy with the Laguna body - its =3D
very
lumpy and difficult to throw, but I have 125 lbs of it, so I am largely
handbuilding with it till its gone.
Third shelf, which was about 7" below the roof of the kiln and the stack =
=3D
was
loaded with 5 slab-built soap dishes and a small bowl made with the =3D
Laguna
body and glazed with a simple clear glaze.
When I opened the kiln, every one of the soap dishes was beyond just
cracked. They looked like they had been sort of torn apart. The small =3D
bowl
also had a crack from the lip down about 1/2 way to the foot.
