Due to having pet birds, as well as not wanting any exposure for my family to the toxic fumes given off when non-stick materials are exposed to high heat, I wish to purchase a new oven that is free of any non-stick surfaces or coatings. I need a basic oven, the typical kind with a 4 burner range on top. Can anyone here kindly recommend such an oven? I am hoping they still exist, lol! Many thanks in advance!
