When you handle molten iron in a blazing furnace nearing 2,500 degrees, "you have to kind of know what you are doing." Wayne Potratz made that point clear as he and his students Friday transformed liquid metal into art at the University of Minnesota's foundry. It was the art department's 45th Annual Iron Pour, an event that turns the foundry into a friendly, Hades kind of a place.
