... in the Bastnäs mineral (later named cerite to celebrate the discovery of the dwarf planet Ceres; F ig . 1 ). The two earths became known as “yttria” and “ceria”. During the next 100 years, through careful and painstaking separation techniques, they would be shown to be mixtures of oxides and, between them...
