A long time ago I bought a stunning whole set of V&B pots & pans. They are very heavy, so I imagine that they are cast iron covered by enamel. But everything sticks, and when you clean them, the enamel scratches sooo easily. I'm beginning to think they're just for "show," and not intended for use. I'm going to give them away, but I was just wondering, since no one ever mentions them here, if anyone else uses/used them?
