I wish I could find out more about this pottery company that made this casserole bowl. It is marked Miramar of Calif. Ovenproof. 305.
It is a gorgeous shade of pink. I did recently come across a picture, that showed that it had a metal wire holding base, for it to sit in.... that I do not have.
But found a picture of the holder here...
I do not hold out hope, I will be able to locate this wonderful holder. But I am happy to at least be able to see what I am missing.
