The story of the word

Ground antimony sulphide was painted round the eyes long before anyone catalogued it as a mineral, and the Greek στίβι is generally traced back to an Egyptian word for that black cosmetic. Latin reshaped it as stibium, which is why antimony's chemical symbol is Sb and matches nothing in its English name. The Ichinokawa mine in Japan produced blades over half a metre long, and museum labels still fight over who owns the best of them.
