Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.

The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

While not as common as other uses, food-grade mica powder is making its way into the food and beverage industry. This type of mica powder is safe for consumption and is often used to create visually appealing decorations for cakes, pastries, and beverages. Edible mica powder can add an eye-catching shimmer to desserts, making them more enticing. As visual presentation becomes increasingly important in culinary arts, the demand for edible mica powder continues to rise, allowing chefs to express their creativity while satisfying the aesthetic preferences of their customers.
