Glass is great because it doesn't stain, hold smells or flavors and you can cut food in it.
Glass pans, like the classic Pyrex bake ware line can not be used on the stovetop, under the broiler, on the grill or in a toaster oven.
Microwave, oven, dishwasher, fridge and freezer safe.
And many come with lids (BPA free plastic).
These lids can not go in the oven but are safe for the dishwasher, microwave, fridge and freezer.
One thing to be careful about with any glass pan is thermal shock, a fancy way of saying that glass pans can't go from extreme temperatures like the oven to the freezer which is bad for your freezer and frozen food anyway.
You should also avoid putting a hot pan from the oven into cold water or on a damp towel to cool.
I cool my pans on a bakers rack or cutting board before serving or storing my meals.
Also, going from freezer straight to the oven with a pan full of frozen food can be bad.
Instead, try lining your pan with foil.
And, as a bonus, lining the pan means that you don't have to keep the pan in the freezer saving freezer space and letting bake other things without needing to cook your freezer meal.
