Moreover, the Mica Video encourages consumers to seek out brands that prioritize sustainability and ethical practices. Several organizations and certifications now exist to help guide consumers toward ethical products. For example, brands that are part of the Responsible Mica Initiative (RMI) actively work to assure that their mica is sourced responsibly, ensuring that suppliers do not exploit workers, particularly children. This movement is crucial in changing the narrative surrounding mica and promoting better practices within the beauty industry.

Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.

4. Experiment with Combinations

Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:

Mica is not just an important mineral in areas of commerce and industry; it holds educational value as well. Studying mica and its occurrence in rocks can help students and researchers understand the complex processes that shape the Earth’s crust. For budding geologists, learning about the formation and classification of rocks like schist and gneiss is fundamental to comprehending the broader aspects of geology.
