The emissivity of metals and oxides. IV. Iron oxide
At this point in time, it is significance to point out that a small amount of work has been done on low and reasonably high temperature emissivity measurements.

effects of surface contamination - on the infrared emissivity
For example, pure water absorbs very little visible light, but water is a strong infrared absorber and hence has a high absorptivity and high emissivity.
Intro to Thermal Radiation
On the other hand, metals generally have low emissivities with aluminium foil and polished brass being examples of materials with the lowest emissivities.
