What about cast iron, is it ok?

On the glassware, they used to make a stovetop set of saucepans out of higher heat grade pyrex, but don't anymore. I think you can still find them on ebay and stuff like that. However, if it is not specifically designed for stovetop use, do not use it there, it can explode into a bunch of little pieces. I've read about that happening to some over at mothering.com.

I feel damned if I do and damned if I don't with this cookware thing. I'm also looking for some glass reusable bottles with wide necks (easier washing) to carry in the car.
