Vanadium pentaoxide (V₂O₅) is a refined and highly reactive form of vanadium that is used in ceramics to create intense and vibrant colors, especially in yellow and sometimes green and brown shades when combined with other elements. This compound is known to provide a luminosity and depth of color that shines through in both opaque and semi-transparent glazes.
Its ability to integrate well into glaze mixtures makes it an excellent complement to oxide combinations, such as chrome or iron, creating complex and dynamic effects on ceramic surfaces. When applied in different types of clays and under various firing atmospheres, this oxide allows obtaining from warm, sunny yellows to deeper, earthy tones, which makes it extremely versatile in decorative projects.
Interesting Fact
This compound has been used in ceramics since the 19th century, when ceramists were looking for ways to intensify the colors of their glazes without resorting to traditional methods.
Helpful Tip
If you are looking for bright colors, mix vanadium pentaoxide with other oxides to explore its possibilities. However, due to its toxicity, it is vital to use proper protective equipment and ventilate your workspace well.
