I have tried every which way to do platters and the best that works for me
is to hang a slab piece on canvas over a barrel. It drapes well and dries
enough to turn and then work on applying legs. They still crack through the
process some of the time.
I also have had good luck with making molds; although they are a lot more
sensitive to cracking, it seems.
My question is: can you take a favorite plate or platter and apply clay to
it and make that as a mold or a platter itself. I've not had any luck doing
trying this. As it starts drying and pulling away from the original, it
starts cracking. I have a couple of rather large platters from which I
would really like to get molds.
Any suggestions?

Spray the platter with "PAM" (canolla oil) or WD-40. No cracking. Just remember that clay shrinks in drying so the platter clay should contact the concave (female) side of the original. I have done this many times. If putting the clay on the convex (male) side - there is more chance of cracking due to shrinkage - but it sometimes works too. Sam in Daly City
