The entire concept of an iron surface of any kind, either a vaguely defined iron crust or a solid & rigid iron surface critically depends on the real, physical nature of the
photosphere of the sun. A stellar atmosphere is the transition region between the stellar interior and the interstellar medium. The photosphere is the restricted region around the temperature minimum of the stellar atmosphere and is the source of most of the visible light emitted by the star. The physical condition of the solar photosphere is derived from observations of
limb darkening, our ability to see the atmosphere of the sun projected against the empty space behind it, simply because the sun, unlike other stars, is really nearby. You can see a schematic illustration of how this works in figure 9.2 of the book
The Observation and Analysis of Stellar Photospheres by David Gray. The figure appears on pages 174 & 175, and can be seen in the Google Books link provided. Unfortunately, the preview does not include figure 1.1 on page 2, which is a nice schematic of the temperature profile of the outer layers of the sun. Placing the arbitrary zero altitude at where the effective temperature of the photosphere is about 6000 Kelvins, the temperature is seen to rise to about 12,000 Kelvins 1000 km below the zero reference, and fall to a minimum of about 4500 Kelvins 800 km above the zero reference. The temperature then rises slowly through the
chromosphere, then passing rapidly through 20,000 Kelvins into the transition region between the chromosphere and the
corona, which reaches into the tenuous interplanetary medium of the solar system.
Chapter 9 of Gray's book, "The Model Photosphere", begins on page 170, and much of it is available on the Google Books preview link provided. This is the chapter which describes in detail how the model photosphere is derived from observations and known physics. It is the rational, scientific counterpoint to the vague & opinionated assertions of Mozina. It is this science, this physics, which utterly destroys any notion of an iron crust or surface on/in the sun.
The laws of thermodynamics absolutely refute any notion of an iron crust or surface without question. This is not a matter of opinion, it is a matter of physics. The attentive reader should not let Mozina get away with fobbing off unsupported opinions as if they were anything other than just that. If he cannot produce arguments as detailed and scientifically complete as the science presented in this book, which science he claims to refute, then his arguments must be rejected in their entirety.
