Ceramic glazing is an intricate art, where the choice of pigment can dramatically influence the final appearance of the piece. One pigment that has gained popularity for its deep, captivating hues is Iron Oxide Blue. Known for its unique ability to produce vibrant, rich tones, Iron Oxide Blue is a must-have for ceramic artists and manufacturers seeking to create visually striking ceramics. Feiyan Pigments, a leading manufacturer of high-quality ceramic pigments, specializes in providing this powerful colorant for all types of ceramic glazes.
In this article, we will explore the role of Iron Oxide Blue in ceramic glazing, its chemical composition, and how Feiyan Pigments can help you achieve vibrant tones in your ceramic art.
Iron Oxide Blue, also known as cobalt stannate, is a chemical compound primarily made up of iron (Fe), cobalt (Co), and tin (Sn). It is a complex oxide pigment that, when used in ceramic glazes, produces a rich blue to blue-green coloration. The unique blue tones are often a result of the interaction between the chemical structure of the pigment and the glaze components during firing. The specific temperatures, atmosphere (oxidizing or reducing), and the glaze composition can all influence the final appearance of the Iron Oxide Blue.
The formula for Iron Oxide Blue is generally represented as FeCoSnO4, combining the natural beauty of iron oxide (Fe2O3) with cobalt and tin, two elements known for their ability to produce brilliant, stable colors in ceramics.
Iron Oxide (Fe2O3): Iron is responsible for producing earthy, red, and brown hues in ceramic glazes, but when combined with cobalt and tin, it helps create the deep blue shades in Iron Oxide Blue.
Cobalt (Co): Cobalt is a key component in many ceramic pigments, offering a wide range of blue tones, from light and vibrant to deep and saturated blues.
Tin (Sn): Tin contributes to the stability and opacity of the pigment, helping it retain its color and texture even in high-temperature firings.
Iron Oxide Blue is prized for its color stability, lightfastness, and resistance to chemical reactions in the glaze during firing, making it a preferred choice for many ceramic artists.

Achieving the perfect shade of Iron Oxide Blue in your ceramic glazes requires an understanding of both the glaze chemistry and the firing process. Here are some essential tips for using Iron Oxide Blue effectively:
The glaze base plays a critical role in determining how the Iron Oxide Blue will appear after firing. A silica-rich glaze provides a smooth, glossy finish that allows the deep tones of Iron Oxide Blue to stand out. Glazes with more alumina (Al2O3) content can help to produce matte finishes, which may be ideal for those looking for a softer, more subdued blue.
The temperature at which you fire your pieces significantly influences the final appearance of Iron Oxide Blue. Typically, this pigment is most vibrant at cone 6 to cone 10 (around 1220°C to 1280°C), but variations in the firing process, such as an oxidizing atmosphere, can bring out the pigment’s rich blue hues. If firing in a reducing atmosphere, the tones can shift, sometimes leading to greenish shades instead of pure blue.
For more intense and saturated blues, use higher concentrations of Iron Oxide Blue pigment in your glaze. Start with a recommended percentage, and adjust based on the desired final result. Feiyan’s Iron Oxide Blue is highly concentrated, so small amounts go a long way in achieving the desired effect.
Feiyan’s Iron Oxide Blue can be blended with other ceramic pigments to create a range of hues, from vibrant turquoise to deep navy blue. Combining it with copper carbonate (CuCO3) can yield a teal shade, while mixing it with titanium dioxide (TiO2) or zinc oxide (ZnO) can produce a more pastel effect.
For manufacturers, Feiyan’s Iron Oxide Blue offers an excellent solution for large-scale production of vibrant ceramic products. Whether you're creating tiles, tableware, or decorative ceramic pieces, this pigment ensures that your products will maintain consistent color across batches and offer long-lasting vibrancy, even after prolonged exposure to light and use.
