This is a beautiful silver-gray.
This mineral is used to add color and shimmer to epoxy resin, soap, candles, cosmetics and even translucent polymer clay. Although mica differs to pigment powder, as its main purpose is to create a sparkling or shiny effect, whereas pigments are the colors themselves.
Mica is derived from a natural stone mineral that boasts shiny flakes. Once the mica stone is ground into a powder, mica powder is created. The powder is basically a soft type of fine glitter that has a coloring or dying effect when it comes into contact with a myriad of different surfaces and materials.
The off white, gray, yellow, or slightly brown mica powders stem from muscovite – a metamorphic rock that contains potassium aluminum silicate. Mica powders routinely used to dye soap are often colored with ultramarines, titanium dioxide, and other oxides to create bright pigments.
Both natural white mica powder and colored mica powder cast a pearly, shimmery, sparkly, and metallic effect when used to decorate or dye a project.
