Best Mica Powder for Resin and How to Use It

Mica powders

Many types of pigments can be used to color resin, however, I love using mica powder for luscious colors and gorgeous sparkle. These naturally occurring particles can help turn your resin creation into any color you can think of! Let's delve into the resin world, determining which mica powder is best for it and explaining how it all works.  

Creating resin crafts and art is a lot of fun. So let's get ready to have some fun and create some amazing, fantastical art!

What Exactly is Mica Powder?

Mica powders

Mica is a naturally occurring mineral that is used to make mica epoxy pigment powder. After the mica mineral has been mined, it is dehydrated and combined with other natural substances such as iron and tin oxide. These substances combine to form a very fine powder, which is then used to dye resin in almost any color imaginable!

While you could use epoxy pigment powder to color your resin, it will not produce the same sparkly results as mica powder. Regular resin dye and pigment powder only color the resin without the reflective and sparkly effects that distinguishes mica powder. The end result of regular epoxy pigment powder is a matte finish. 

Mica powder is a popular option for coloring epoxy resin, when you also want to add some sparkle. This is because of the fact that mica naturally adds glittery shine as well as rich, vibrant color. As a result, swirl formations and natural glimmer transform resin crafts and pours in an instant.

The Most Effective Mica Powder for Resin

You've probably seen many mica pigment powders around, whether in a store or while shopping for crafting supplies online.

What is the difference between mica powder and resin dye?

We are all aware that these substances are used to add color to resin. Both regular dye color and mica powder are relatively easy to find, both online and at your local craft store. Each product will have a different effect and aesthetic as the end result in your resin projects.

Mica Powder will produce a shiny, glossy finish with shimmering effects whereas resin dye is just plain color that will produce a matte finish.

Mica Powder and Resin Mixture

When using resin dye vs mica powder, you will notice a difference right away. As a result, the resin will have an opaque look and the mixture will have no sparkly or swirly effects. Resin will simply take the dye's color. You can adjust the transparency of the resin by adding only a small amount of resin dye.

How to Mix Mica Powder with Resin

Most epoxy kits include two components: resin and a hardener.

Mix the resin and hardener according to the package directions. Typically, you should mix these ingredients for 5-8 minutes to ensure everything is thoroughly mixed. Then you can add your mica powder.

There are two ways to incorporate mica into resin:

Stirring:

You can manually mix mica into the resin with a mixing stick or use a paint-mixing drill bit (useful for larger projects). Thoroughly combine. Make sure the mica powder is evenly distributed throughout the resin.

Pre-Mixing:

Pre-mixing the mica with a smaller amount of resin or in a tiny bit of alcohol can be beneficial to get the mica powder dissolved really well before adding it to a larger volume of resin. Add a small amount of resin or alcohol into a small cup. Incorporate the mica powder into the resin or alcohol solution until completely dissolved. Then combine this with your main epoxy solution.

Guidelines for how much mica powder to mix into resin

How much to mica powder do I add for smaller resin projects?

As a general guideline, use 1 gram of mica powder per 1-5 ounces of epoxy when doing projects that require small amounts of resin. One gram is roughly one quarter teaspoon. Adding more mica powder to your resin will obviously produce a darker and more opaque color, while less mica powder will produce a more transparent appearance.

To achieve that rich, pearlescent color in your jewelry pieces, you will typically require a higher amount of mica in your resin.

How much mica powder do I need for larger projects?

If you are doing larger projects that require large volumes of resin (over half-gallon) use about 1-3% mica powder (by weight) in the total resin mixture. For example, 1 gallon of epoxy weighs approximately 9 pounds; thus, if you want a more opaque color, use about 3-4 ounces of mica powder per gallon of epoxy resin. Use less mica powder if you want a more transparent finish.

Making Custom Colors:

If you wish to make custom colors, just pick two or more mica powders in different colors and add different ratios of these powders into your resin to create unique, custom colors.

Achieve Swirly Colors in Resin:

Here's how to create swirls of different colors in resin.

After combining the resin and hardener, divide the mixture into two smaller containers (or more if you want to swirl 2 or more colors). Combine your mica powders with your resin by stirring thoroughly.

When you're ready to pour, start with the base color. This will be the color with the highest volume. Then add one more color at a time. Before allowing the epoxy to cure, swirl the colors with a toothpick or skewer.
