That's what it's for.

Don't go bananas, bring it up slowly. But you'll be fine.

Yeah its fine

Thanks!

If it is the enameled cast iron cookware they are famous for, you will be fine. There is no problem with the thermal up shock, but they do warn about thermal down shock of the enamel(cooling quickly, like placing a hot pan in water).

when it has been in the refrigerator overnight or do I need to let it warm up on the counter first?
