after reading qfan's link, I found this:[p]Do not place aluminum foil, or anything else, between the oven rack and pizza stone (or tiles). The radiant heat will be reflected, instead of being absorbed, which keep your stone from reaching and maintaining proper temperature. I made this mistake thinking that foil would keep crumbs from falling through the cracks onto the oven floor. Big mistake. I was never able to get my crust to brown properly.[p]There's the answer on the aluminum wrapped platesetter.[p]Next time, no foil and all is well...[p]Thanks qfan.
