Donna, Nancy gave you good advice on the tar paper bats. Tar paper and
roofing felt are two names for the same thing. I would just add that I
have found l5 lb weight is about right. Too thick and stiff doesn't
work very well. I cut mine in various sizes by placing a plate or
saucer or salad plate on the felt and cutting around it with a box
knife. About l inch beyond the foot of the piece you are making is
about right. Too much and the tar paper tends to wrinkle as it dries.
Once you have wired off between the bat and the wheelhead, you can lift
the smaller bowls off onto a ware board with a wide cement trowel. I
use bats with tar paper for plates and pie plates, but for intermediate
sizes, I use about an 8 or 9 inch tar paper bat, and after wiring it
loose, I pull the bat and pot onto a small board with needle nose
pliers, and then onto the ware board. When you get into the swing of
production throwing your right hand reaches out for a little smear of
throwing slip and puts it on the wheel at the same time you grab
another bat. You will want to turn the pots sooner than you might if
you had thrown them on plaster or other bats. As soon as the rims are
firm you can turn them and peel off the tar paper. I always scrape off
the excess clay while the tar paper is still damp. You will find these
save you a lot of space in a small studio.

wet clay and start at the center and spread it across the wheel while

is a
very thin layer. I then place the felt on the wheel and take my weight
sponge, start from the center and press down and out until I go off the
edge of the felt as the wheel is turning. Once you get it, it is so
easy. The felt doesn't move at all. I use this method for plates as
well
but I put the felt on a bat. Using it for plates, helps when it comes
to
wiring off, I can let the plate sit up a little longer and there is no
fear of wiring through the bottom of the plate since you wire off
between
the bat and the felt. When the plate has set up enough, you just peel
the
felt paper off. I read the latter part in an article in clayart but I
don't remember which month and I have been using it ever since. The
article shows a lot of clay being put on the

enough.

That was very clear and helps a lot. It sounds ideal and I can't wait
to
find where I 'stored' my left over roofing felt for making this new tool
(I certainly hope we are talking tar paper here or else I have the wrong
material in mind).
Thanks!! Donna
