Sorry, typo. I meant to say vantablack will heat up slightly faster, not the other way around.

- yarg 7y agoSo at some constant rate proportional to the delta between the material and the environment? Essentially I'm wondering at what point that isn't fast enough to avoid combustion. Since it consists of densely packed nanotubes, I'm guessing that oxygen will be in short supply deep down where the light is converted, so it might need to be close to the point where the heat is high enough to disintegrate a nanotube. I'd imagine that's be a rather high temperature.
