ABOUT NATURAL MICANatural mica powders are made from a group of naturally occurring silicate minerals mined from a variety of rock to include granite. Many natural mineral mica powders appear lighter in color when applied on skin. Natural micas are widely used in cosmetics, DIY craft projects, art pieces and more.PARTICLE SIZE INFORMATIONSlice of the Moon carries mica options that range from 5 µm to 500 µm. The smaller the particle size in micrometers or microns (µm) the more fine the powder and the more coverage or hiding power. Conversely, the larger the particle size the more coarse the powder which provides more of a glittering effect. The larger particles provide less coverage or hiding power and have generally more luster.Creating your own cosmetics? When it comes to cosmetics, especially for those intended to be applied around the eyes, the smaller the particle size the better (within the 150µm or less range). Slice of the Moon mica powders are fine to ultra fine in size, with most all being well suited for bronzer, highlighter, coloring for lotion, body butter, and other cosmetic applications.MIXING PIGMENTSWhether it’s creating your own vibrant watercolor pigments, adding a bit of a golden hue to a sunscreen, or making your own resin pigment paste, mica pigments are a great way to achieve your preferred color! As a general rule, we recommend adding a very small amount at a time to your base or medium. Repeat as needed to achieve your desired hue.
