The high temperatures of the parabolic are such that you can use shiny steel pots and pans (those that are more common) but it will give you a little more advantage if you have a dark colored pot/pan. With a parabolic it is more recommendable to use the heavier gauge steel pots, because the thinner variety will scorch and burn your food more easily, especially the thin aluminum, which is also known for health related issues and concerns.
