Recent studio experiments visualising relationships between minerals and the #ElectromagneticSpectrum.

Samples collected from sites of geophysical prospecting for #TechnologyMetals and fragments of electronics are lit with prisms used to separate the visible spectrum into its consituent colours.

Doping prisms with specific metals enables them to transmit certain frequencies of light. The reflection spectra of raw ores can be used to target #CriticalMinerals.
