Greetings, Has anyone thought of replacing the metal mesh dome with one of ceramic ? or better even a bed of ceramic stones. I will write in detail when I have more time.

It even has a higher emissivity than stainless steels in the 0.7-10 micron wavelength range (red visible light - mid-IR range), meaning that it will emit more EM radiation than a stainless steel at the same temperature. http://www.pyrometry.com/emissivity_materials.php You say that silicon carbide has a higher emissivity and will emit more EM radiation at the same temperature than stainless steel. I think that this is the critical point: how to get more radiation at the same temperature. Thanks. Paul
