Technical Field

The invention relates to the field of iridescent glaze, in particular to iridescent pearl glaze and a preparation method thereof.

Background

The iridescent glaze is a ceramic glaze which can show different color effects, or colorful rings with multiple colors, or multicolor iridescent effects, or pearl luster and interference luster, or silver luster on the surface of the glaze in sunlight. In the process of forming the iridescent glaze, crystals or crystalline films are separated from the surface of the iridescent glaze under certain thermodynamic conditions, and the refractive index, the reflection and the absorption characteristics of the crystals and the glass phases are different, so that visible light with various wavelengths incident on a glaze layer generates optical path difference to cause light interference, and the iridescent effect is caused. The traditional iridescent glaze is easy to cause environmental pollution in the production process, and the surface gloss and the flatness of a finished product are still to be improved.
