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.

When selecting a mica supplier, it is critical to evaluate their level of expertise and experience in the industry. Historically, companies with extensive backgrounds in mineral extraction and processing are better equipped to deliver high-grade products. They possess comprehensive knowledge of geological formations and employ advanced extraction techniques, ensuring the mica they produce retains its desired properties. Such suppliers often have a deeper understanding of the specific needs of different industries, providing tailored solutions that align with unique business requirements.

The application of mica in candle making is relatively straightforward. Candle makers can sprinkle mica powder directly into melted wax; starting with small amounts and gradually adjusting to achieve the desired intensity. Alternatively, mica can be mixed with a small amount of oil before being added to the wax; this method helps to prevent clumping and ensures an even distribution of color. The result is a candle that not only looks beautiful but also retains the quality of the wax and fragrance.
