You're kidding, aren't you? I could adress you exactly the same questions! This kind of argumentation is leading nowhere; I provided you my explanation and you're asking me "how do I know" whitout yet reading it and whitout trying to evaluate my arguments?
I don't know what material is, but my evaluation doesn't depend on the material but only on it's temperature.
No, he's not kidding. If you look back in the thread at least six or seven of us have answered the sunspot question, with references, and he keeps coming back with the same questions. As to what materials are involved, I provided a table back here:

That is, very hot hydrogen/helium with a bit of other elements. Michael seems to insist that sunspots are literally dark, and that only neon emits light, so he rejects anything that would indicate otherwise. *In my opinion* he doesn't understand the concept of "blackbody temperature." A number of references have been provided on sunspot physics and the effect of the sun's magnetic field, but he rejects that as well. For what it is worth, yours is one of the more detailed answers. Nicely done.
