Spectra
Sodium — Spectra Mug
Sodium speaks in yellow. A single bright doublet near 589 nanometres — the colour of a flame test and the old sodium lamp.
What you're wearing
Printed edge to edge on an eleven-ounce mug, the emission band wrapped with its wavelength scale. Spectra reads matter by its light. One line does most of the talking.
