Cobalt Oxide

Cobalt oxide is a highly concentrated material used to obtain intense and stable blue shades in glazes, slips, and ceramic pastes. It is resistant to high temperatures and both oxidizing and reducing atmospheres, ensuring durable and uniform colors. Its versatility allows it to be mixed with other oxides to create chromatic variations, such as greens or violets. In small amounts, it provides subtle bluish hues, while in larger concentrations it generates deep and vibrant tones. It is used in the manufacture of earthenware, stoneware, and porcelain, being an essential material for high-quality ceramic decoration.
