Glass Pie Pans -temperature?

[Guest guest]

Hi All, I wanted to bake some gfcf pumpkin pies for my family in the

glass pans I have. I baked some last year, but I don't remember the

maximum temperature glass pans can withstand in the oven. My pie

crust recipes call for 400-450 degrees in the oven. Does that seem

okay for a glass pie pan? They are blue glass pans--possibly

Corningware. My mind is a blur right now. Any information in

appreciated. Thank you. Rose
