Also known as a micrometer, a micron (µm) is a metric system unit of measurement. A single micron is 1/26,000 of an inch or one millionth of a meter. Often used to measure very small, micro-sized particles. Slice of the Moon carries various powder products that range from 5 µm to 500 µm. The smaller the particle size in micrometers or microns the more fine the powder.

To put this information in perspective, a single strand of human hair (on average) is about 100 µm in diameter. Unaided and with the naked eye, most of us cannot see anything smaller than 40 µm.

what is
mica powder?

Mica powder is pigment powder that comes in a variety of colors and particle sizes. In short, mica provides the color and shimmer found in many everyday products.

Mica is found in cosmetics, paint, bath bombs, epoxy resin projects, candle designs, DIY creations, or jewelry — there is no limit to what can be done with a little mica powder.

mica powder questions

Yes. Our mica products are child labor free, an issue that we take seriously. Nowhere in the sourcing, mining, production of our products is child labor utilized. We are third-party audited.

Yes. Our products are never tested on animals and do not contain animal products.

Mica is generally safe. However, because it is a small particle, it can be hazardous when working in tight spaces with no ventilation. Always wear gloves and a mask when working with mica powder in large volumes or for extended periods.

Mica is naturally reflective, and it’s widely used to add shimmer to cosmetics products, including blushes, eyeliner, eyeshadow, foundation, hair and body glitter, lipstick, lip gloss, mascara, moisturizing lotions, and nail polish. 

Yes! Mica powder is great for homemade cosmetic products such as lipstick, lip balm, lotions, moisturizers and bronzers. Mica is also perfect for coloring arts and crafts projects like epoxy/resin crafts, paper crafts, acrylic paint/fluid art, bath bombs, soaps, and pottery.

Mica is a natural mineral. It’s ground into powder and mixed with oxides to change its color. Mica is prized for its reflective properties, which add shimmer and vibrant color to a wide range of products. Shop our natural mica collection.

Synthetic mica powder is made from Fluorophlogopite, a man-made mineral, which has a crystalline structure that mimics the properties of natural mica powder. Shop our synthetic mica collection

how much to use?

How much mica to use? As a general rule, a little bit goes a long way and it’s better to begin with a small amount, then add based on desired effect.

These are some suggested percentage ratios of base or medium to mica.

glow-in-the-dark pigment powder questions

The particle size range for our Glow-in-the-Dark line is between 20-30 µm. To put this in perspective, a single strand of human hair (on average) is about 100 µm in diameter. Unaided and with the naked eye, most of us cannot see anything smaller than 40 µm.

The main ingredient in our Glow-in-the-Dark Pigment Powder line is Diatomaceous Earth. Diatomaceous Earth is an organic fossilized silica powder used widely from beauty products, supplements, to a natural insect deterrent for gardeners. 

It just needs a bit of light! Use a black light, the sunlight, or an LED light to get the powder energized or charged. UV black light generally results in a faster charge (3-5 minutes), followed closely by direct sunlight (best with 7-10 minutes). Fluorescent and incandescent lights will charge the luminescent powder but may take a bit longer (20-30 minutes).

Achieve reusable long-lasting glow effects by first charging the powder with black light, direct sunlight, or LED light. Note that the pigment can be charged multiple times. Luminescent pigment is a kind of light energy storage powder which can glow in the dark after absorbing different visible light under 450 nm.

Yes! It charges best when paired with a clear or light-colored medium that allows the light through.

For example, if you are mixing the powder with nail gel - look for a clear or lighter gel color to mix with the Glow-in-the-Dark Pigment Powder. The nail color will charge when you’re out and about, resulting in a glow once you enter a darker room.

Yes. All but our Neon Blue Green colors have a decomposition point at temperatures greater than 200° C (392° F). The Neon Blue Green color has a decomposition point at temperatures greater than 300° C (572° F).

glitter powder questions

Both serve to create beautifully crafted products. It’s all about what you’re mixing it with and what you envision as your end product.

SOLVENT RESISTANT GLITTER POWDER is crafted with durable coatings designed to maintain the integrity of the glitter, withstand higher temperatures, and avoid breakdown in many corrosive solvents. Solvent resistant glitters work well in nail polish or nail lacquer products, epoxy resin projects, and other creations that require a more resilient glitter type.

NON-SOLVENT RESISTANT GLITTER POWDER is glitter powder designed for creations that do not call for high temperatures and solvents. Uses include many creative applications that create beautiful shimmer and shine in a wide variety of colors without harsh solvents. Alternatively non-solvent resistant glitter powders are wonderful for the blending and delicate bleeding effects. 

A helpful test to identify if the glitter powder you have is resistant to solvents is to test it with a solvent! There are all sorts of solvents to try, but a general rule is to test it with a fairly corrosive solvent like acetone or other solutions found in cleaning products.

Soak glitter in the solvent. If it does not bleed or dissolve within a 10-20 minute time period, it’s resistant! However, note that some glitters will begin to break down in certain solvents after several weeks. It really depends on the particular solvent and the exact nature of glitter particles themselves.

Yes, but use with caution. When it comes to cosmetics, especially for those intended to be applied around the eyes, the smaller the particle size the better (roughly 150µm or less).

Most all of our glitter are considered ultra-fine with particle sizes ranging from 25-40µm in size.

Yes. To be safe, we recommend not heating the glitter beyond 100° C (212° F).
