"Cobalt" Definition
Word Fact:
German miners who encountered cobalt were no fans of the metallic element. Maybe that was because, when it was heated, it would fill the mine with smoke and kill them—or at least cause permanent health issues. (Cobalt often combines with arsenic and will release the poison if heated.) When the metal was confirmed as a distinct element in 1780, it was given the appropriately malicious name of "kobold," the German word for "goblin."
