The story of the word

Humphry Davy isolated the metal by electrolysis in 1808 and named it from baryta, the earth it came out of. That name came from barytes, what mineralogists called heavy spar, a white stone that surprises the hand with its weight. The same βαρύς gives the baritone, a heavy voice, and the barometer, which weighs the air.
