Yes, both cornbread and scones can be baked in glass baking dishes.
Of course you can .... I actually prefer to bake it in a glass pan it doesnt get as dark that way. Still tastes the same. Yummy!
PUT special stuff in it.
Yes, how much, depends on the thickness.
Yes, when you cook with a glass bowl, it might crack when overheated.
Collards and cornbread
You are not likely to find a rectangular dish with a glass lid. Try Corningware. Amazon.com has a large selection of cooking pans.
Yes, you would spray (grease) a glass dish when baking cheese cake. But the proper pan for cheesecake is a metal spring-form pan. This is a round cake pan with sides that can be removed from the base.
It's basicly just a baking dish that can hold up to 750mL
Yes, you can use a baking bag in a large baking dish, as long as the food you plan to bake will fit into the dish you want to use.
Personally, some options I like are cornbread or beans

You don't really 'use' a baking dish. You can put food on it, tin foil, aluminum foil, non-stick spray, etc.
