Spectral laboratory

How to identify a substance by its spectral lines and unlock new recipes.

An ore sample, a creature part, a gas or the light of a star give a spectrum. Match its lines with the references — the real lines of substances — and you learn the substance, and with it the recipes made from it.

Hands-on

What to doHow
Feed a sampleput it into the laboratory: it burns in the arc, and the prism spreads the light into a spectrum on screen
Match a referenceslide the references along the ruler until their lines sit on the peaks of the spectrum
Mark the unknownmark all strong lines of the single unknown substance
Checkthe laboratory says “matches” or “does not match” — without telling what is wrong

The lines are real — from the reference tables: hydrogen’s Balmer series, the sodium D lines, calcium H and K, oxygen bands. Where the game takes liberties, the reference text says so. If a sample holds two unknown substances, you need a simpler sample.

On a telescope, the spectrograph shows which bodies have air and life.
