Ceramic and Glaze Colorants - The Spruce Crafts

Yellow iron oxide is another form of ferric oxide; although its raw color is different, it is chemically identical to and acts the same as red iron oxide. Black iron oxide (ferrous oxide, Fe 3 O 4) is courser and generally not used. Crocus martis is an impure iron oxide which can be used to produce speckled, rough, or spotty effects.

Copper: The mineralogy of Copper - Mines, Minerals and More

Most widespread minerals containing Copper; This list of minerals containing Copper is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Copper mineral species.

Oxide minerals increase the undisturbed and remoulded strengths of the sensitive marine clays. In Eastern Canada, the oxide mineral contents of sensitive post-glacial marine sediments are greatest in the near-surface, where weathering has occurred, and decrease to an approximately constant value (in the order of 1%) where unweathered.
