A visual effect produced by illuminating a table salt doped alcohol flame which produces the typical orange-y sodium spectrum with a monochrome sodium
spectrum electric light. See attached images, check out the linked short video.
Now. Where can I get strontium, barium, boron and potassium spectrum lamps- Or other suitably tunable light sources.
And how did I avoid hearing about this effect before?

It seems Physicists and Chemists do not talk with each other very much.
That is a good demonstration of Absorption Spectroscopy. https://en.wikipedia.org/wiki/Absorption_spectroscopy Sulaiman - 23-2-2023 at 19:24

I think that a low cost option is a broad spectrum lamp (tungsten halogen, HID etc), lenses and/or mirrors, a diffraction grating and a couple of
adjustable slits.
And a lot of miscellaneous materials and work.
A spectroscope in reverse.
I'd expect very low light levels, and a not truly monochromatic light spectrum, but may be zdoable.
If as a hobby project then I'd consider making the narrow bandwidth light source easily reversible to be a spectroscope?
And later as a spectrometer?
I'd consider it, but probably never do it
Other than a few industrial applications, and very specific educational purposes,
I guess that spectral lamps would be high cost per use in an amateur setting.
