I think it is is glass. OTOH, the price of the pan and lid is 120 to
170 dollars, so even the lid is probably too much for me.I cleaned the pan and put it in the car, and I'm on the path to stopping at every thrift shop in town. I don't think I'll find it quickly, but otoh, I really don't want to order one and find out it doesn't fit
Thanks for all the help.
I'll try to post back when I get something.
