The more I learn about black body radiation, the more I realize a reflective surface is exactly what you don't want.

High reflectivity minimizes photonic heating, high emissivity minimizes particle heating. No need to radiate heat away if you aren’t hot in the first place. Also, as metal heats up to yellow/red/white, it stops being reflective.
