My crock pot was passed down to me by my mother, and it seems to be pretty old. It's a Corningware brand slow cooker with three settings, low, hi, and auto. I know it's at least as old as I am (almost 20) and I've only recently started cooking in it for myself. Does anyone know about this brand in particular, or other old crock pots? I'd love to see if anyone else is still using this one. I'm also curious if there's anything I should watch out for concerning older crock pots.
