Once extracted, mica undergoes several processing stages to refine and enhance its properties. The raw mica is first crushed and ground into fine particles, an essential step for its integration into various products. Depending on the intended use, it can be purified to remove impurities, enhancing its value. For instance, in the cosmetics industry, high-purity mica is preferred for its shimmering and reflective qualities used in eyeshadows, blushes, and other beauty products.
Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:
미카 파우더를 왁스 멜트에 추가하는 방법은 매우 간단합니다. 일반적으로 왁스를 녹인 후 미카 파우더를 소량씩 추가하면서 잘 저어주면 됩니다. 이때, 미카 파우더가 고르게 분산되도록 충분히 저어주는 것이 중요합니다. 만약 미카 파우더가 덩어리져서 섞이지 않는다면, 왁스의 온도나 저어주는 방법을 조절해보는 것이 필요합니다. 중간 온도에서 천천히 저어주면 더 균일한 혼합이 가능합니다.
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.
