Generally it doesn't change color while the flame is on it, but after it has been quickly cooled by water. I guess I need to use an infra-red thermometer the next time we do it to know exactly but my guess is 400-500 degrees is hot enough. Ironically, we cure powder during powderpainting at 400° in our oven.
