Black Iron Oxide (Pottery Colourant)
Colourants can be added to glazes to get the desired coloured effects. Unlike stains, colourants react differently in each firing. A wide spectrum of colours can be achieved by mixing them with other colourants, opacifiers & stains.
Name: Iron Oxide (Fe2O3)
Appearance Colour: Black
- In Slips: 0.5%-8%
- In Glazes: <15%
Output Colour: Varied
Stability: Relatively stable when compared to yellow iron oxide.
Additional Information: 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. 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
Caution: 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.
