I use them all the time! I pick them up for a buck or so a garage sales or thrift stores, cook them to just above full-fuse temp before using them (they're usually filthy), then kiln wash. I've had a few break if I ramp too fast but for the most part, they're just kiln shelves.

I once visited a factory that makes mullite kiln shelves and furniture. Sitting next to all those was the pile of pizza stones. They are identical to kiln shelves, and require the same separator to prevent sticking.

The one I have is only about 1/2 as thick as my regular kiln shelves. Is this normal? Do I need to ramp up more slowly? Georgia

My pizza stones are thinner than my kiln shelves, too. I don't ramp faster than 400°on them now as I did break a few by ramping at 600°an hour.

Thanks Valerie. I have been afraid to use the pizza stone because of the thickness. Georgia

My common sense says that a thinner shelf would be less prone to heat shock, not more prone, just like glass...

I don't mean to contradict Valerie at all though. In her kiln 400dph may well be a good rate to ramp up. All kilns are not the same relative to this sort of thing.
