The feature size of the matte vs shiny sides are much smaller than the wavelength of the bulk of the radiated light in either a microwave or conventional oven.

- cwillu 8mo agoLook up the emission spectrum for a body at the temperature of a typical oven element: yes, it starts emitting some light that is visible, but the bulk of the energy is still in the IR band.
