Yellow iron oxide

Yellow iron oxide is a pigment that ranges in shades from yellow to brown in glazes and pastes. During firing, it can transform into red or black iron oxide, depending on the temperature and atmosphere of the kiln. Its use in ceramics enhances color intensity and provides earthy and natural effects. It also acts as a flux in some formulations, promoting vitrification and glaze adhesion. Its stability and versatility make it ideal for decorating earthenware, stoneware, and porcelain, achieving warm and expressive finishes on the pieces.
