Black Iron Oxide (FeO) is one of the most common colorants in pottery, and it is widely used because it can produce a variety of colors. As a glaze component, it can create varied effects depending on the conditions. In general the following occurs with iron oxide:
oxidation firings produce red iron oxide
reduction firings produce black iron oxide
The amount of iron oxide present in a glaze will affect the colors as well. Suggested concentrations of iron are as follows:
0.5- 8% in slips
up to 15% in glazes
Because the ranges of concentrations are so broad, we recommend that you consult one of the many useful glaze recipe books that are available for reference.
Black iron oxide is the reduced form of red iron oxide. In this reduced form, it acts as a flux, meaning that it it promotes the formation of glass within the glaze.
In its powdered form, black iron oxide can cause skin, eye and respiratory tract irritation and sensitization. Please use protective coverings when handling this chemical.
