SUMMARY
The discussion centers on estimating the temperature at which a surface glows white hot, starting from a known temperature of 500°C, where it glows red hot. Participants suggest using Wien's Law to relate the peak wavelength of emitted radiation to temperature. The consensus indicates that to achieve a white hot appearance, the temperature must be significantly higher than 500°C, as the peak of the blackbody radiation curve must shift into the visible spectrum's center. This shift is necessary for the surface to emit all visible wavelengths with similar intensities.
