Mica is a group of silicate minerals known for their perfect cleavage, allowing them to be split into thin, flexible sheets. These minerals are typically found in igneous and metamorphic rocks. The most common types of mica are muscovite and phlogopite, both of which are prized for their light-reflecting properties. Natural mica flakes are produced by mechanically separating these minerals from their host rocks, resulting in thin sheets that can be ground into various sizes.

Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.
