Mix-n-scrapers!!! LOVE THEM!!! I have a classic bar pan that I use for everything, including roasting a chicken. It was the single best item I brought over from the US and it JUST fits in my oven here. I also really like my grill pan and the classic pots and pans. Those are still, sadly, in the US. My sister is a consultant, so I have a lot of Pampered Chef stuff.
Happyutopia, your mom should have spoken to the consultant who sold her the stoneware. Always keep your receipts for anything, as there's a guarantee on most Pampered Chef (possibly lifetime on the stones) and she could have returned it to get a new one.
