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.

The common characteristics of mica group minerals are: layered silicate minerals, monoclinic crystal system, a few trigonal crystal system, the crystals are pseudo-hexagonal columnar, plate and sheet; The aggregate is scaly and foliaceous. It has a set of extremely complete cleavage, along which it is easy to peel into sheets. Therefore, the shape of mica is usually regarded as sheet.

In short, there are significant differences between natural mica powder and synthetic mica powder in production methods, color and appearance, performance characteristics, application fields, and price and cost. Synthetic mica powder is superior to natural mica powder in terms of high temperature resistance, transparency, electrical insulation, stability and mechanical properties, while natural mica powder has more advantages in resource acquisition, cost and color. When choosing which type of mica powder to use, you can consider the high temperature resistance of the required material, electrical insulation performance, transparency and color requirements, evaluate the mechanical strength and hardness of the required material, consider chemical stability and other different application scenarios and technical requirements to make a reasonable choice.

Mica has a wide range of uses, in ancient China, it is often used to do traditional Chinese medicine, the ancients even think that taking mica: a year to remove all diseases (heavy metal poisoning), three years of long service, husband into a boy (body scrap), Zhongshan uncle Qing suit, over time can become a cloud (soul ascension). However, in the era without glass, the transparency of mica makes it a better decorative material, for example, we are familiar with the mica screen candle shadow deep, the river gradually falling Xiaoxing sink. Mica screen is low, tassel tent is small and mica calf car.

Mica is a new non-metallic crystal material, a national key new material, with heat insulation, insulation, high temperature resistance characteristics, is an important material in aerospace, rail transit, nuclear power, wind power, aircraft carriers and other high-tech fields, but also electrical equipment, wire and cable, household appliances indispensable insulation material, in the national economy and national defense construction plays an important role.

Mica powder, known as industrial monosodium glutamate, is widely used. With the continuous development of technology and application market, and some new requirements have been put forward for the quality of mica powder, so synthetic mica powder has been developed. Compared with the natural mica powder processed by natural mica ore, and the synthetic mica powder synthesized by using a variety of raw materials through high temperature reaction and other chemical methods. What are the advantages and differences between them?

In conclusion, painting with wax melts and mica opens up a world of creative possibilities. The interplay between the melted wax and shimmering mica allows artists to produce works of art that are rich in color, texture, and dimension. By embracing this technique, artists not only create stunning visual experiences but also delve into the enchanting world of transformation and inspiration that lies at the heart of artistic expression. Whether for personal enjoyment or public exhibition, this unique method of painting offers an exhilarating way to communicate ideas and emotions through art.

4. Screening The ground mica is screened to ensure uniform particle size. Proper sizing is crucial for achieving the desired shimmer and appearance in culinary applications.
