I dont have aluminum foil nd i have to bake a piece of paperSo what would happen
If the paper is dry, nothing will happenYou cannot bake paper in a microwave ovenPaper does not absorb microwavesTo the microwave oven, the cavity is empty and running a microwave with an empty cavity for a long time can cause overheating of the microwave oven It is not clear why Lee26loo thinks you will get sparkingNo such thing will happen.
