The story of the word

Herodotus wrote about the Κασσιτερίδες, the Tin Islands somewhere off the northwest of Europe, and admitted he could not say where they were; Cornwall is the usual guess. The Greek word is not native and may have come in along the trade route from the east, tracking the metal itself. Tin is what turns copper into bronze, so a dull brown crystal underwrites an entire age.

In a sentence

The streams below the granite still carry cassiterite, which is how the deposits were found.
