Other phases were also identified with insufficient amounts ashematite (Fe2O3) and wustite
Iron in a black tattoo ink is associated with the use of magnetite and wustite
(iron oxides) as components of the ink.
Independent teams at the University of Chicago and Osaka University in Japan recently squeezed wustite and found that it conducts electricity at pressures and temperatures similar to those found in the planet's outer core and lower mantle, the layer just above the core.
Pockets rich in wustite may exist at the core-mantle boundary, where the mineral may transfer heat from the core into more shallow depths, says Chicago's Rebecca Fischer.

It leaves a very fine layer of existing Wustite
- a sheen - on the surface of the strip helping to protect the surface for many months against any deterioration.
Decrease of concentration of wustite
FeO in the melt in the course of the reduction process causes decrease of iron monoxide activity and, as a result, complication of the metal reduction from it and increase of the reducer consumption .
When these alloys are exposed to a source of oxygen (O) such as air or water, the O may react with the iron (Fe) in the ferrous alloy to form iron oxide (FeO), also called wustite
Our thermomagnetic evidence does not preclude formation of another, nonmagnetic, iron oxide, for instance wustite
(FeO), which may have a strong effect on the black color.
This reacts with the iron to form wustite
(FeO ), which in turn reacts with the silica fibers to form a layer of fayalite (2FeO-SiO).
