Zinc oxide is a versatile compound in ceramics, mainly used to adjust the texture of glazes and to achieve matte and satin finishes. This material is especially useful in the formulation of satin or semi-matt glazes, providing visual smoothness and a surface that is pleasant to the touch. In addition, zinc oxide acts as a stabilizer in glazes, helping to reduce the risk of cracking, a valuable quality for the durability of utilitarian and decorative pieces.
This oxide can also influence the final colors of glazes when combined with other colorants, achieving opacity effects or even crystalline effects under certain firing conditions. In high-temperature glazes, zinc oxide contributes to improve the stability and resistance of the finish, allowing glazes to maintain their appearance and texture even under conditions of intense use.
Interesting Fact
Zinc oxide is also a common ingredient in products such as sunscreens, due to its ability to block UV rays, making it a widely used material in various industries.
Helpful Tip
Use zinc oxide in small amounts if you are looking for a matte effect in your glazes, but avoid using too much, as it can dull other colors and affect the final texture of the glaze.
