Iridium Element-77 T-Shirt

Named for Iris, the rainbow goddess, iridium was named for the colorful salts it forms. Its signature uses include spark plugs, crucibles, electrical contacts, and the standard meter bar in historical metrology. It is also linked to the asteroid-impact layer at the dinosaur boundary, a major scientific clue in the study of mass extinction and impact geology.
