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.

Beyond the realm of cosmetics, artists and crafters have also embraced mica powder for its versatility. It can be mixed into paints, resin, and clay to add vibrant colors and shimmering effects to various artistic creations. The powder easily blends with mediums and can be used in techniques such as alcohol ink painting and soap making, allowing artists to experiment with textures and finishes. The wide range of colors available—from soft pastels to bold jewel tones—ensures that there is a shade for every creative need.

2. Artistic Creations Artists often utilize shimmer powders in painting and mixed media artwork. By mixing the powder with mediums such as acrylics or resin, artists can achieve a unique texture and luminosity that transforms their creations. These powders can bring ordinary artwork to life, offering depth and a dynamic play of light.
