acceptable pot loss during bisque

Warren MacKenzie showed me his new bats for large platters that he
made from 1/2"x4x8' Hardibacker #500 last week when we visited. He
said he was having trouble with the big platter's rims lifting up
because they dried so much fast than the base. He bought two sheets.
Said Nancy had to help him get them out of the truck because they
were so heavy. Guillermo cut them in circles and Warren gave him a
sheet for his labor. I am wondering if the new Dremel Trio would be
good for cutting these circles:

The only time I ever lost a pot in bisque was when the pot was not
quite dry when I loaded it into my electric kiln---it exploded.

I throw larger pieces on Hydrobats. They retain moisture for a long
time, even in Winter when the humidity is low.

As soon as a piece can be handled and releases easily from the bat, I
place it upside down on its bat. At this point the bottom is too soft
to be trimmed but the moisture in the bat keeps the rim from drying out.

No rim cracks.

really well but you do need to wet them slightly before use or the clay
releases during throwing. I found that out the hard way. They do act much
like plaster bats in that they release the clay when it is ready for
trimming. This is very nice when you are doing platters and plates.

What is the difference in a platter and a plate as far as size goes? I know
that platters are used for serving and plates for eating but where is the
break point from plate to platter? Also, what is the general consensus on a
"large" pot? Anything over a foot? Anything over 18"?
