If you are an avid crafter, artist, or makeup enthusiast, you’re likely familiar with the diverse range of pigments and shimmers available. Two of the most common types are mica powder and pigment powders. While they may appear similar, they possess distinct properties and uses. Let’s dive into the differences between them and how you can use them to elevate your projects.
Mica Powder: The Sparkle of Nature
Mica powder is a natural mineral known for its shimmering qualities. This fine powder is created by crushing mica minerals into a soft dust. It is popular due to its pearlescent shine, providing a subtle shimmer and a touch of color.
Uses: Mica powder is widely used in makeup products because of its natural composition and gentle effect on the skin. It is perfect for eyeshadows, lip balms, and face powders, giving a natural glow. In crafts, it is a preferred choice for soap making, resin art, and candle making, adding a hint of sparkle without overwhelming the base color.
Pigment Powders: Bold and Vivid
Pigment powders are highly concentrated colorants. Unlike mica powder, they are not natural and are manufactured to achieve vibrant and consistent colors. Pigment powders are recognized for their density and intensity, making them ideal for projects that require bold and prominent colors.
Uses: Perfect for painting, pigment powders provide artists with a rich palette. They blend well with materials like oils, acrylics, and watercolors. In the realm of crafts, they are excellent for coloring resin, making custom nail polishes, or dyeing fabrics. Pigment powders offer a depth of color that mica powders cannot match.
Blending Mica and Pigments: The Best of Both Worlds
To achieve the ultimate creative experience, mix mica powder with pigment powders. This blend allows you to achieve the density of pigments with the sparkle of mica, making it perfect for unique art projects, custom makeup, or even paints used in automotive applications.
Safety First
While mica and pigment powders are generally safe to use, it is always essential to handle them responsibly. Wear a mask when working with powders to prevent inhalation and check product specifications for any additional safety measures, especially when used in skincare products or cosmetics.
In Conclusion
Whether you’re looking for the subtle sheen of mica powder or the bold colors of pigment powders, both can elevate your projects to new heights. Explore our range of pigments to find the perfect match for your next creation. Remember, the only limit is your imagination!
Understanding Pigment Powders, Mica Powder, and Their Blend
There is a variety of mica powders, pigment powders, and mixtures between the two, and I hope the information below helps you determine what you want to use in your various resin projects.
Sometimes the terms mica powders and pigment powders are used interchangeably. However, they are not the same. The powdered materials are either pigments, mica powder, or a mixture of the two — often particles that will suspend in a medium, such as those used with resin or various acrylic mediums.
Mica is shiny. Pigment powder alone is not shiny. They behave differently. However, they are also sometimes blended together in the same packaging to achieve a different appearance. This might mean that the powder you purchased will not function in the way you expect it to. If it contains more mica, it will color less than if it has more pigments added.
Mica is a natural mineral with shiny flakes, often ground into a powder to become mica powder. The shine present in the flakes is why mica powders tend to be more sparkly. They are often used to give metallic effects or a pearl-like glow.
Mica powders often have some colors in them, but alone, they are not ideal for coloring things because their main purpose is to create shimmer or glow. Mica powders cannot create a solid coverage of vibrant colors alone.
Pigment powders are crushed colors. The pigments are the colors themselves, often referred to by their more common names, such as ultramarine blue, cadmium red, cadmium yellow, and titanium white. There are also synthetic pigments (less expensive) with different names, such as pigment blue 15. Pigments are what manufacturers use to give paint its color. They are neither shiny nor reflective. Pure artist pigments (the true colors) are actually very expensive, which is why pigments you buy from cheaper online suppliers are often mixed with filler materials (like chalk) to make the color last longer.
It can get a bit confusing because, in recent years, the term pigment has sometimes referred to mica and synthetic mica particles. So, you could say that mica is a type of pigment, but pigments are not mica. In fact, these materials are two entirely different and not very alike substances.
Interference pigments are synthetic mica and have a special coating on them. Chameleon powder also has a special coating that reflects light in various colors, depending on the light angle.
Interference colors are made by coating mica with titanium dioxide. They look almost white when you look at the powder. Chameleon powders are mica that also changes colors, but they don't look white; they have visible colors in them. The mica in chameleons is treated with layers such as titanium dioxide, iron, and other assorted metal materials. Both interference and chameleon colors change when light or angles change, but interference pigments are more subtle and only have the titanium coating. Chameleon is more dramatic, especially when used over a dark colored resin. Both powders are often brushed onto the mold just before pouring the resin into it.
Pearlescent mica powder is typically non-colored, equivalent to white or silver. However, mixing pigment with mica powder simply results in a mixture of pigment and mica. The mica itself will not become colored.
Colors of interference mica are powders that produce different colors depending on how light hits them... thus showing different colors when viewed from different angles (one color reflects and one color transmits)... So technically, all opalescent or iridescent colors are created by interference.
It seems that most interference colors are single colors (“interference” + color name).
These are white-based powders that produce a shine of any color they are called.
Benefits of Chemical Toll Manufacturing
When applied to white or lighter surfaces, the interference colors are less apparent, and their “flip” effect (on dark colors) is more pronounced.
If you put an interference gold color over white clay, the piece may appear colorless against any light or white backgrounds, but you’ll notice a gold shimmer when rotated under light.
Flaky or interference red powder appears white on light backgrounds, but when used on dark or black colors, you will notice a red shimmer.
When applied extremely thinly over dark colors, it does not show the whiteness you see in the jar at all; just the reflective color.
Simply put, when you apply interference colors over dark colors, they come alive, allowing you to see them and creating a beautiful result as detailed above. Glitter-like products work the same way, allowing them to be seen over dark colors, but with a beautiful sparkle instead of pearl-like effects.

Glitter powders ...
Often when we buy glow in the dark products, we are not necessarily purchasing what we think we are, and some only glow based on charge from sunlight during the day, while others only glow when near black light.
Both can be weak or strong in glow, based on various factors.
Fluorescent pigment colors appear intensely in daylight but won't be visible in the dark unless exposed to black light.
Phosphorescent pigment colors will glow in the dark, but only after being exposed to a light source, including sunlight or by placing them under a light bulb to charge the glow pigment. This glow may last a shorter amount of time than the light they were charged with.
Should you be unsure of the color you wish to use and there is no description where you purchased it, you might need to test it first. Or contact the seller to learn more about whether it is considered non-shiny (which is more opaque in resin when used in sufficient amounts), or if it’s more transparent.
Some mica powders are made to be more transparent, and you may need to add more of that powder to achieve greater color saturation. Remember the important resin-to-color ratio. The recommended ratio for colorants is 2-10% of the resin, and if you use more, it may disrupt the chemical balance of the resin, affecting its hardness (also potentially causing excessive heat). Sometimes it may be necessary to add pigment if there is a desire to change the transparency level of the color.
Many mica powders and pigments can also be used in acrylic mediums. See a separate article and blog for more information.
Sometimes, people suggest using eyeshadow shades as pigments in resin. While this can sometimes work, it is not a pure pigment. It will take more powder to achieve a pure pigment depth, so you'll need to monitor your ratios. Additionally, some eyeshadow may contain other added ingredients (moisturizers or oils) that are not resin-friendly. Always test small projects first. They are not ideal for resin.
