A conventional oven that is! hehe Ok, ok, so growing up we always had electric ovens, and the one we current have at our house has these cool even flames breathing out. I captured two shots that I liked.
The yellowish-orangish flash on the right was that the flames floating on the top of the oven while set on broil would hit something flamable and flash as it burn out the energy. I stared for awhile to grab one.

Here I did more of an angle, which made it very reminiscent of a bird or plane with the glow of the oven light illuminating it as the sun rises.
