Flame Emission Spectroscopy

Analyzing combustion chemistry by observing characteristic atomic emission lines from heated elements. Different fuels, salts, and metal contaminants produce distinct spectral signatures visible through a diffraction grating or prism. Forge flames, gas burners, and doped flames each tell a different story in discrete wavelengths.

Cobalt Glass Between Yellow and Everything Else

Sodium contamination hides every other element in the flame—until you hold cobalt blue glass up and the forge lining confesses it's made of strontium.
