I just found this piece. I love the knob on the top and the shape at the bottom of the bowl. I couldn't see any markings when I bought it, but I have found that it is a Federal casserole dish. Yes, I would love it in my kitchen, but I thought it would also look wonderful in a vintage bath -you could fill it with cotton balls, round soaps, or just have it for looks! Most of the styles I have found online have a pattern, being plain, this one would go anywhere. I'll be listing in on my website soon.
