There appears, to me, to be a push to change the subject of the discussion to "solar moss" when the initial question was in regard to "solar mass," a question which still has not been adequately addressed.
Composition is ancillary to mean density, which is simply a measure of mass divided by volume. It appeared, in initial discussion of this element, that it was deflected by claiming structure was important. True. However, this would not affect mean density: mean density would limit structure. For instance, if there were to be a 6.5 g/cm^3 shell, the interior of this shell would have to fall well below the mean 1.4 g/cm^3 density, or the shell would have to be very thin.
The other issue is temperature, which is necessary to get the black body radiation. If we relied on electrons and emission spectra of plasmas, we would indeed see a large spectral spike in the Neon ranges - which do not add up to a solar spectrum, regardless of how many "valence electrons" one might include.
Note the absorption lines in the solar spectrum correspond to helium and hydrogen, and that Neon's emission lines cannot account for a full solar spectrum, no matter how they are sliced.
Another point raised was the incompatability of sunspot temperatures and a solid "ferrite" surface.
Regarding umbral temperatures:
4800 Degrees Centigrade
2000 degrees Kelvin cooler than the surface
Wikibooks registers 3500 degrees Centigrade
4500 Centigrade
4600 degrees Centigrade
Mr. Sunspot says 4000 degrees Centigrade.

...A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings, and intense magnetic activity. Although they are blindingly bright, at temperatures of roughly 5000 K, the contrast with the surrounding material at some 6000 K leaves them clearly visible as dark spots. Interestingly, if they were isolated from the surrounding photosphere they would be brighter than an electric arc.

The only place that I can find, curiously, that is below 3500 degrees (Centigrade or Kelvin) is the openly editable current Wikipedia. The minimum from all other located sources including a former Wikipedia sunspot entry (3500 Kelvin) is still above the vaporization temperature of iron.
