The pans are Air Bake pizza pans. I got mine from Target. I have 2 of each for the large & small BGE's. We use them for pizzas and other items as well.
We make the pies right on the pan. No messing with parchment paper, corn meal, etc. I let the pizza stone or stones get hot for 45 minutes or so. I put the pizza and the Air Bake pan right on the stone. After a few minutes i slide the pie off and directly on the stone. When the pies are done I slide the pie bake on to the Air Bake pan...easy peasy...
I hope that answers the questions. Thanks
