Knowing how one mica powder is different from another&#;beyond merely color&#;can help you decide which ones to use and which ones would be best suited for your artistic endeavors.

Because mica powders actually come in a variety of different textures, colors, and mixtures, it's worth explaining it in a little more detail.

In this article, we'll discuss how mica powders differ from one another, but also how they correspond.

Are All Mica Powders the Same?

No, all mica powders are not the same.

Mica powders vary widely in quality, color, particle size, and finish, which can significantly affect their application and the results they produce.

Mica: A Group of 37 Different Minerals

Mica is actually a group of 37 different silicate minerals. Despite that number, many of these minerals are not commonly used for mica powder products. There are two common mica minerals used for a variety of functional purposes: phlogopite and muscovite.

Beyond those two, there are several other that get used as well, often for aesthetic purposes, such as in the creation of pigments.

Natural Vs Synthetic

The differences begin with the source of the mica itself. Natural mica, mined from the earth, comes in various grades that depend on its purity and the presence of other minerals. Synthetic mica, on the other hand, is created in a lab and can be produced to a consistent standard, often resulting in a more uniform shimmer and being free from the natural impurities that can affect the color and quality of natural mica.

The processing of mica into a fine powder also contributes to the diversity among mica products. Some mica powders are finely ground, offering a smooth, subtle shimmer, while others have a coarser grind, providing a more glittery and reflective finish.

The size of the mica particles plays a crucial role in how the pigment disperses in a medium, whether it be paint, resin, or cosmetics. Finer mica powders are typically used in applications requiring a silky texture and even coverage, such as in foundations or eyeshadows, while larger particles are used for bold, sparkling effects, such as with our Glitter Series of mica powder pigments.

An Expanded Range of Color

Furthermore, mica powders are often coated with various dyes or pigments to expand their color range. Natural mica's color palette is generally limited to earthy tones, so manufacturers coat the mica with titanium dioxide, iron oxide, or other colorants to achieve a broader spectrum of hues. This coating can also affect the powder's refractive properties, which determines how it reflects light and, consequently, what color it appears to the eye.

Cosmetics and Safety

The safety and suitability of mica powders can also vary, particularly in cosmetic-grade mica, which must meet strict purity standards to ensure it is safe for use on the skin.

In essence, while all mica powders share the basic properties of the mica minerals, their differences in origin, processing, and finishing result in a wide variety of powders to suit different needs and applications.

What Are Common Uses for Mica Powder?

Mica powder can be used for a variety of things. Functionally, it can provide insulation for electricity, and it has high heat resistance.

Aesthetically, it is often employed in artistic endeavors for its colorfast, non-fading properties. Mediums such as epoxy resin, paint, clay, candles, and more are all receptive to mica powder pigments, allowing it to impart its vivid, shimmering tones to these kinds of creative works.

With its insoluble nature, mica powder is able to blend well with many different types of liquid mediums, without dissolving. It retains its reflective form, which is what provides the gentle sparkling effect when exposed to lighting.

Mica Powder vs. Pigment Powder - What is the difference?

Recently I&#;ve noticed much confusion about the difference between mica powder and pigment powder. Both can be mixed into and used to add color to resin, soap, candles, and translucent polymer clay. They are both colorants and can be used to color the surface of polymer clay. But they are not the same thing. Here&#;s the difference.

Mica is sparkly. Pigment powder is matte. They behave differently. But online listings are often confusing and they&#;re sometimes sold mixed together in the same packet. And that can mean the powder you bought won&#;t work as you expect.

Mica Powder

Mica is a natural stone mineral with shiny flakes. When mica is ground into a powder, you get mica powder. Mica powders are therefore sparkly, sort of like very fine glitter. They&#;re used to give a metallic or shimmery pearl-like effect. They come in many colors. Pearl Ex is a popular brand of pure mica powder. (See a color chart of all Pearl Ex colors here.) While mica powders do often have color, they&#;re not optimal for coloring things because their main purpose is to create sparkle or shine. They won&#;t create a solid wash of bright color.

Pigment Powder

Pigment powders are ground-up colors, sort of like powdered colored chalk. Pigments are the actual colors themselves and have names such as ultramarine blue, cadmium red, yellow ochre, and titanium white. There are also artificial pigments with names like Pigment Blue 15. Pigments are what manufacturers use to give paint its color. They are not sparkly. Pigment powders are excellent at coloring things (this is their job, after all). Pure artist&#;s pigments (pure color) are fairly expensive, so pigments you buy from cheap sellers online are usually mixed with fillers (such as chalk) that make the color go farther. (For the nitpickers among us&#; in recent years the word pigment occasionally refers to mica and synthetic mica particles. Therefore it can be said that mica is a type of pigment, but pigments are not mica. But in reality, these materials are two different things and are very dissimilar materials.)

Confusion

Confusion happens when sellers of craft materials try to gain buyers by using confusing keywords. You often see listings in online marketplaces &#; like this one on Amazon (Affiliate Link &#; learn more here) &#; where the terms are used rather loosely. In this case, I&#;m not exactly sure what you&#;d get. You might get pigments, you might get mica powder, or you might get a mixture. And while we&#;re at it, these colorants are not a dye, contrary to what the listing says. Pigments and dyes are completely different things, as explained in this article.

Used in Cosmetics

Both mica powders and pigment powders are used in the cosmetics industry. In fact, a combination of pigments and mica powder is used to create eye shadow, blush, and powdered foundation makeup. These can be used with polymer clay. You can read about Using Eye Shadow with Polymer Clay here. Cosmetic supply companies are excellent sources of both pigments and mica powder. But choose a reputable company to be sure of exactly what you&#;re getting.

They Behave Differently

While both mica powders and pigments can be used to color the surface of polymer clay, they do behave quite differently. Knowing which material you have will help you know how to use it in your clay project. These are both incredibly versatile materials that can be used in so many ways beyond adding rosy cheeks to a cherub. For example, about a third of the veneers in my 100 Days Project are done using mica powders and pigment powders. Here&#;s an example of a veneer using only pigment powders, mica powders, and a stencil.

Do you want to know more about using mica powders and pigment powders on polymer clay? You&#;re in luck. I wrote a huge 90-page guide called &#;Powders &#; using mica, pigments, metal powder, and dyes with polymer clay.&#; It explains all about these beautiful powdered colorants and how to use them in and on polymer clay and explains how to use them on both raw and baked polymer clay. This information will also be invaluable if you use these powders with other media. Check it out, I know you&#;ll love it!
