i tried my first bag of that new clay body.
very porcelain. white, baby pooh stuff.
i made 6 big bowls, and 6 small bowls...turned ring
feet, and put them with about 30 other pots from my
standard stoneware clay to dry.
all of the big bowls cracked in circular patterns, fell apart.
talk about S cracks...wow. 2 of the small ones cracked too.
not one of my clay pots cracked at all. and, i may add that
the porcelain was well thrown, consistent.
no more of that stuff for me. it also altered it's shape
when drying.
i realize now that it takes very slow, covered drying. not for me.
it also left a very hard, dense frit like substance at the bottom
of my throwing bucket. hard as a rock.
it may be great for others, but all that special handling, and
shape altering would not suit me at all.
i am going to throw a couple hundred pounds of michael wendt's
helmer body this week. i am sure it will be a much better result.
now that i have a clean wheel, well i will have to make some more
white clay pots. never waste a clean wheel. (the axner test wheel.)

Can we possibly be using the same clay? I have had no cracking
problems at all with Southern Ice, and I didn't baby the drying of the pots
I made at all, and surely Colorado is a lower humidity climate than Minnesota.
Southern Ice porcelain is by far the best throwing porcelain clay I have
ever used. and I've been throwing porcelain constantly for 23 years. It stands up on the
wheel like a champ.
