Have any of you used the Temp-tations bakeware? QVC sells it and I saw an infomercial this morning about it. It is very pretty but I am particularly interested in the 9x13 dish. It is deep and comes with a stoneware cover lid (can also be used as a cookie sheet or serve tray) and a plastic one. A lot of good reviews on QVC, but there are some that had a problem with it cracking in the oven.
