This is one of the four unglazed ceramic (stoneware) pans I use regularly (two large, one medium, one small), and I cannot say enough about how wonderful they are.

I use them mostly for roasting vegetables, but they’re also ideal for pizza, at least by my lights.

This one is the most seasoned of the four, in both senses (they should be washed as you would a good cast iron pan, that is, without using soap).

I don’t recall how I first heard about them, more than 8 years ago, but I bought mine on line. They are made and distributed by the marketing company, Pampered Chef.
