Hi Cindy,
You may have commented about this already and I missed it. You posted some
questions about canvas bats a while back. Was the following quote below,
the reason you were getting cracking when you were using the canvas bats?
I had just started experimenting with canvas bats (also paper, plastic, and
other found items) when I had to take my studio out of commission so we
could start working on our basement. I can't wait to get back and get going
again.
Sometimes I would have this problem. While I was trying to center, the
'bat' would slide off center. Or especially on plastic, the lump of clay
would slide off the plastic and the plastic would twist. Wasn't sure if it
was the way I throw, too much slurry under bat, too wet slurry, etc. Anyone
else encounter this?
Sincerely,
Nikki Simmons

When the plate has stiffened up enough, peel the canvas bat away. Just be
sure to peel it away as soon as possible or your plate may crack, just as it
would if you left it uncut on a rigid bat.

Hi, Nikki.
Yes, I think the smaller projects were cracking
because I didn't remove the canvas bats early
enough. Vince suggested this might be the problem,
and I haven't had any trouble with them since I
returned home last week. I'll let the list know if
the cracking persists, but I'm pretty sure that
removing the bats early enough has solved the
problem.
As for the bat slipping around, yes, you are using
either too much or too little moisture. Probably
too much. They (like everything else) do take a
little getting used to, but they're well worth
learning.

Nikki - The problem of clay sliding off plastic bats, in fact any
non-porous material, including the metal wheel head, is simply a
result of moisture (water or slip) between clay and surface. Have
both surfaces dry, start with your clay in a cone shape (rather than
ball), set clay near center of wheel head (or bat) and with wheel
going at slow speed, run your finger along the base of the clay to
seal to the wheel head. Have my students do this, don't have to slam
the clay down, never have clay come loose from the wheel.
