Metallic (Glaze)

Metallic (Glaze)

Metallic glaze in ceramics is a type of finish that simulates the appearance of precious metals such as gold, silver, copper or bronze. This effect is achieved by incorporating metallic oxides and special lusters into the glaze composition, which react during firing to produce a shiny, reflective finish. Metallic glazes are especially popular in decorative and luxury ceramics, where a sophisticated and elegant visual effect is sought that adds aesthetic value to the pieces. The creation of a metallic glaze requires a precise formulation that allows the metal contained in the glaze to react properly under firing conditions. For example, the use of copper oxide can produce a green metallic finish, while cobalt oxide can generate blue or black metallic tones. The kiln atmosphere, whether oxidizing or reducing, also plays a crucial role in the manifestation of colors and metallic luster. In a reducing atmosphere, metal oxides can lose oxygen, changing their color and increasing the luster, which is essential to achieve the desired metallic effect.

Interesting Fact

Iznik ceramics in Turkey are famous for their metallic finishes that combine vibrant colors with metallic reflections, creating pieces that are both functional and exquisitely decorated works of art.

Helpful Tip

To obtain a uniform and shiny metallic finish, it is crucial to carefully control the glaze composition and firing conditions. Make sure that the metal oxides are well distributed in the glaze mixture to avoid concentrations that may cause staining or variations in gloss. Pre-test small pieces to adjust the glaze formulation and kiln conditions to ensure reproducibility and consistency of the metallic finishes on your ceramic pieces.
