Cobalt ochre, cobalt-ochre (Cobalt ocher in American English) or ochre of cobalt (German: Erdkobalt) — a common name that was widely used in mining and craft environments until the end of the 19th century for at least two cobalt-containing secondary ore minerals: asbolane and erythrite. They were often used with the addition of a clarifying color adjective or a clarifying mineral form adjective to avoid confusion.
For example, Robert Jameson divided cobalt ochres into four classes: black cobalt-ochres, brown cobalt-ochres, yellow cobalt-ochres and red cobalt-ochres. In turn, each of the color forms of ochre had two or three varieties. Black cobalt ochre had two main forms, which were widely distributed in the mines of Europe: earthy black cobalt-ochre and indurated black cobalt-ochre. Brown or yellow-brown cobalt-ochres varied in composition, sometimes being a mixture of black and yellow cobalt ochres. Yellow cobalt-ochres often appeared in association with various forms of red cobalt-ochres, as well as nickel ochres. Finally, red cobalt ochre was known in three mineral forms: earthy red cobalt-ochre, radiated red cobalt-ochre, and slaggy red cobalt-ochre.
