Burnt umber is the calcined, or heated, version of raw umber, which is a natural brown to reddish-brown earth pigment. Heating raw umber dehydrates the iron in the pigment, which results in better material stability. This pigment contains primarily iron oxide and manganese oxide, as well as traces of other oxides, and is generally a bit darker than other similar pigments, such as ochre and sienna.
Even though this is a commercially processed version of this pigment, there may be slight variations between batches, as it is a naturally occurring mineral. The term umber doesn't refer to just one specific color, but rather to an entire range of colors.
The term 'umber' is derived from the Italian 'terra di ombra', or earth of Umbria (an Italian region where umber was initially mined).
In ceramic applications, burnt umber is typically used as a body stain in light- or white-colored clays.
