Burnt Umber is the calcined, or heated, version of raw umber, which is a natural brown to reddish-brown earth pigment. In ceramics, Burnt Umber is most commonly used as a body stain in light/white-colored clays. This pigment contains both iron oxide and manganese oxide, and is generally a bit darker than other similar pigments, such as ochre and sienna.
