The only thing I have heard about exploding glass bakeware is the junk made in China which some of the newer things are. I tried to find lids for some of my corning ware only to find they weren't available. I finally found a place called "World Kitchen" that had some. I didn't realize they were the Chinese replacements. I ordered two, but the don't fit well. It was after that that I heard about the exploding Chinese bakeware so I don't use those lids in the oven.
