If I understand you, a shiny hot surface will be a poor emitter of
heat, even if it is much hotter than its surrounding air?
How much a surface emits (radiates) is independent of the temperature
of the surrounding air, it just depends on the surface temperature.
At a given surface temperature, a more reflective material will emit
energy at a lower rate than a black surface would.
