Zinc Oxide

Zinc oxide is a material primarily used as a flux and opacifier in glazes and enamels. Its incorporation improves the durability and chemical resistance of the pieces, as well as influencing the texture and shine of the finish. It promotes the formation of smooth and homogeneous surfaces, reducing defects such as crazing. It can also modify the thermal expansion of the glaze, helping to prevent stresses in the ceramics. In combination with other oxides, it contributes to the generation of varied visual effects, such as matte or satin surfaces. It is an essential component in the production of earthenware, stoneware, and porcelain.
