Hello everyone,
indeed forget bats is what I found out when I saw someone throw on a piece
of canvas... no pins, no clicking sound, no warping... Hmmmm...
Make sure you shrink the canvas before cutting it and iron it -- this stuff
usually gets pretty wrinkled. Waterproof glue is used to outline a band
where the circle is to be cut. The glue will keep the threads from coming
apart after the canvas is cut and lodging themselves in the clay.
Once ready to use the dry canvas is applied to the wheel head with slip or
what was left at the bottom of your slurry bucket from the last time your
threw. You won't need much. You are now ready to throw as usual.
When ready to cut the pot off, just cut between the canvas and the wheel
head; no more messy cuts. Slide the piece off the wheel head.
Once leather hard, the canvas peels off the bottom of the pot leaving a
slightly rough bottom since the canvas is not perfectly smooth. It
actually doesn't need to be trimmed unless you choose to.
One disadvantage is that unlike the bat, you can't just plop the canvas
back on the wheel head and keep going after you have removed it. The other
is that if you throw bigger than the wheel head, you still will need a bat;
it's only good for smaller items.
I was told that this technique was learned from Kathi Cobb, a Boston potter
a the time.
It might be worth a try if you don't like bats :)

Yes, I have learned from my mistakes...
I can reproduce them exactly.

A variation of the technique Fabienne describes with the canvas is to use
squares of tar paper as "bats." I did this a lot when throwing large orders
of planters, back in the bad old days.

Canvas bats work very well for many applications. I don't go to
any trouble to make mine, just cut squares smaller than the
diameter of the wheel head. I believe Vince Pitelka wrote a very
detailed, careful explanation of these, also, some time back,
and it is probably in the archives.

Quite right. There is a thread "Throwing on Canvas Squares" in
September/October 1998 on the topic if anyone else is interested. Thank you.
