Let the platter set up a bit before removing it from the wheel . . . reduce wheel speed and let it spin for a few minutes, then remove.

I use this lifting practice to flip the platters several times as they dry.

I experimented with a lot of different bats before selecting the ones I use now. They are the Hydro Stone bats from the Ceramic Shop in PA. Here is their contact info:

I buy their seconds at a considerable discount. They don't always have them but they are definitely worth waiting for. They look and work like plaster bats but they are much stronger and don't have the chipping problems plaster has. Platters do not warp on these bats and the other big advantage is that the pieces release quite nicely from them so you do not have to hassle with cutting off a 20+ inch wet platter - which I find to be a huge hassle as well as another potential spot in the process to ding the rim or worse.
