Ann -
You may have discovered a new system for using the canvas squares. No one
else I have ever known of has had any luck getting them to stick when they
are wet or damp. I have been using the canvas-square system since 1969, and
I have always dried them completely between uses. The idea there is that
the when you apply a thin smear of gritless slurry to the wheelhead and
press the canvas square in place, the dry slurry from the last use absorbs
the moisture from the wet slurry, cinching the canvas down to the wheelhead
very securely when you squeegee it with your rubber rib. I have had
students try to re-use canvas squares while they were still damp, and their
pots often slip off the wheel in rather spectacular fashion.
But, more power to you if you have found another way to make this work. But
I think Gayle Bair is right. If these squares were stored damp, they would
mold and decay very quickly.
This really is a non-issue. There is no dust problem with the dry
slip-coated canvas squares.

Vince- I am using squares on particle board, not on a wheelhead. Most
likely the bat is sucking up the extra moisture as I squeegee the canvas to
seal it. I did find that if the top of the canvas is too wet, naturally the
clay ball doesn't want to stick, so I remove extra moisture with a rag until
it feels right. I am making no attempt to keep my squares damp- it's easy
enough to re-slip them. I just thought if Linda was worried about dust they
could stay damp, but I'm sure you're right- they might mold (as Gail also
said) and there's no need.
Good firings,

I cannot follow the logic. If handling dry clay covered squares is okay how
do I convince students of the need to wash tools after use , clean their
wheels at end of class and convince an administration that damp mopping
floors is a need not a want?
Linda -
This really is not an issue, and I expect that your students will understand
the difference. There is no dust created as the canvas squares dry on a
rack, and the dry slip coating is tight on the surface and produces no dust
in the small amount of handling, and as soon as you apply it to the
wheelhead there is moisture present and thus no dust. I do not know what I
have to do to further convince you. There simply is no dust problem with
these canvas squares. There are many other areas of studio practice where
you have to worry about dust, and it sounds like you are very diligent in
that regard, and that you set a very good example for your students. So if
you think the canvas bat system sounds good, go ahead and use it in your
studio, as long as you can arrange a suitable system for drying the canvas
squares.

Hendrix, Taylor J. on sun 20 jun 04
Hey Linda (and Vince):
I'm imagining a class of 4th and 5th graders rushing in to class, eager
to start. They have to wait while others get to class so they fiddle.
And what can be more fun than smacking the edge of the wedging table or
the splash pan with a dry canvas square and watching the billowing
clouds form around you? I share your concerns with a class of young,
young neophytes.
I so wanted to wash the cloth covered boards we use for our summer
pottery class BEFORE the students came in to class, but every time I was
too slow. I watched the first day as students took their pin tools and
rubbed off the dried clay into sinister piles of clay flower. Oh Lawd,
give us strenth.=20
