I wouldn't do that. baking dishes are cheap -fling it out and get asnother.
Use a casserole dish
A Casserole.
it depends on the dish, but 5-10 minutes
you cut your parents in halves and bake them
Yes, so long as the dish in ovenproof, the word ovenproof or ovensafe will normally be printed on the underside.
It is a pan or deep type of dish that is used to bake cakes in.
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.
Yes, you can bake in the oven instead of a steamer. You will need an ovenproof dish with a lid and a large baking tray in which to put water in.
If the bottom of the dish says oven proof than yes, if it does not than I wouldn't risk it. The dish itself would be fine but the paint or sealant might not be if they are heated.
If you using a convection microwave to try to bake a cake, it is best to use four ramekins spaced 5 inches apart instead of a single baking dish. Lightly grease or spray each dish an fill half full. Bake for 5 minutes and then shake each dish to release any bubbles. Bake an additional 5 minutes and test for doneness. If need be, cook an additional 3 minutes. If you want to bake a single large cake, convention ovens are not recommended. If you do use a convection oven, turn your temperature down by 25 degrees.
That might depend upon what egg dish recipe you are talking about. If you are going to bake it the next day, refrigeration should be fine. If it can be frozen and you're not going to bake it for several days, you should probably consider freezing it.
As long as the dish isn't chipped or showing lead, it should be just fine. Apilco dishes are of superior quality, even the vintage dishes.
