The mica process is a multifaceted journey that highlights the mineral's indispensable role in modern industries while underscoring the pressing need for ethical sourcing and sustainable practices. As the demand for mica continues to grow, so does the responsibility of industries and consumers alike to ensure that this valuable resource is obtained in a manner that respects both people and the planet. By supporting sustainable initiatives and seeking transparency in the mica supply chain, we can contribute to a future where the benefits of mica are enjoyed without compromising ethical standards or environmental health.

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.
