I didn't use an oven, per se, but as a kid, I'd read a book from my grandparents' time or so - Lucy Fitch Perkins' The Cave Twins - and in that book, the children "roast" eggs in the coals of their cave fire. My grandmother let me do this in the fireplace only after we'd wrapped the eggs in foil first, in case of explosions. They came out a bit cracked, but otherwise, much like boiled eggs. It was one of those sentimental adventures.
