I've been under the impression that my stoneware pan is made of the same material as pizza stones. At least, the company my pan is from offers a pizza "stone" from the same material. I'm baking some bread tonight and put the pan in a cold oven and turned the oven on to 500F. I let the oven run for a bit to get it nice and hot before I threw the dough in.... when I opened the oven door, my pan was smoking and went from a tan color to a dark brown. It honestly looks burnt. Did I ruin my pan? Is there a way to salvage it? I honestly don't do much bread or pizza baking.... I'm hoping this is just a beginners mistake I can recover from. Thanks in advance for the advice.
