It's called "Donabe" in Japanese.
Casserole sounds little too snobby for the thing.
It supposed to be able to cook on stove.
I was told not to do that, so it is just another Japanese style serving bowl.
I dropped the lid, right before I was putting it on the shelf, so it could be fired...
I like the band style nob, and the spotted glazed color.
