I don't have many details on this item, probably purchased originally in 2006 or 2007. It is a Jan Barboglio casserole dish. We have been the only items of this item and it has been in storage and never used. Unfortunately, it is out of the box. I am not sure about the material this is made of, but other similar Jan Barboglio items are listed as iron so that is what I went with. If you know more than I please let me know. I have tried to accurately represent the dimensions. The glass dish is listed as 2 quarts, and the total piece is a little over 9" in diameter.
