Modeled on Joeseon period Korean ceramic inkpots, this desktop spectrometer is made of porcelain and lined with felt. Samples are introduced in the top funnel, and the “eyes” are pointed towards a light source such as a fire, or the sun. By looking into the square hole, you can see the spectrum of light passing through the sample you’re examining, next to a “blank” sample for comparison.
The spectrometer, still incomplete, requires a diffraction grating that could have come from contemporary materials; I’ve considered using iridescent feathers, fish skin, beetle carapaces, or even the surface of bubble, but have yet to make a final decision.
See a prototype below which demonstrates the comparison of 2 samples in a similar manner:
