Magnesium carbonate is a ceramic additive valued for its ability to modify the texture, appearance and properties of glazes. It is primarily used to achieve matte and opaque finishes, which create less reflective, soft-touch surfaces, ideal for a rustic or natural look.
In addition, magnesium carbonate reduces the viscosity of the liquid glaze, facilitating uniform application in techniques such as airbrushing and dipping. It is also combined with other fluxes and opacifiers to produce visual effects and complex textures, making it a common ingredient in earthenware, stoneware and decorative pieces seeking a unique and sophisticated finish.
Interesting Fact
Magnesium carbonate, in addition to its use in ceramics, is a component used in industrial products such as gymnastics and sports powder, due to its ability to absorb moisture.
Helpful Tip
When working with matte glazes containing magnesium carbonate, be sure to apply thin coats to prevent the surface from becoming too rough or the glaze from cracking during firing.
