Jed, I don't think this is correct (about it needing to be white hot). When I examine the colors, they almost border on being too hot.
White hot puts you up in the 6000+C range according to Wikipedia. Or am I misunderstanding something? http://en.wikipedia.org/wiki/Color_temperature Jed wrote: I have not endorsed these results. I know little about IR cameras. I did point out that the color is wrong, at least in the photograph we have seen. It should be incandescent white. I also pointed out several ways to determine whether there is an error, such as comparing the temperature to the thermocouple, and looking for large differences in different zones.
