Gee whiz. I've been baking all the bread products in our house for 25+ years and have never purchased anything special. I just go to Lowe's or The Home Depot and buy unglazed terra cotta tiles. They're quite inexpensive and work wonderfully. Plus if, for any reason, you break one, it won't break the bank.
