In my last coaster post, I went over some important resin basics. This time we are going to focus on adding color! What better way than with this unicorn glitter coaster? Go back to my Rose Gold Coaster post for all of the important starting info.

How to Color Resin

Three small cups with a little bit of epoxy resin in each, one has three drops of opaque pink dye next to an empty silicone mold

Stirring up one of the cups of resin which is now pink with a popsicle stick

After mixing approximately 8 ounces of resin, I poured some into four little cups. One for each color I wanted to use. A little goes a long way with these pigments! So just add a little at a time and stir. For the white, pink, and purple I used a few drops of dye/alcohol ink in each.

Adding tiny amounts of blue mica powder to a small cup of clear resin.

For the blue I used this powder pigment.

Four small cups of glittery resin with popsicle sticks sticking out of them. The resin colors are pink, purple, blue, and white.

Once I had the colors how I wanted, I dumped my glitter in and stirred.

I used the leftover glitter mixtures from this Easter Jar Project!

When casting in a silicone mold like this one, keep in mind you’re looking at the bottom. For this unicorn coaster I started by putting down big spots of color.

Silicone coaster mold with pink, purple, blue, and white glitter resin poured randomly in mold.

I continued adding in spots of color until the surface area was covered. Dripping little bits of color all over.

Adding more white glitter resin with a popsicle stick to coaster mold to fill in empty spots

Then, I continue adding more to fill the mold to the top. I poured the white all over the bottom. Next, I use my heat gun to blend the colors.

Heat gun pointed over full silicone mold to pop bubbles and mix around the colors.

Afterward, I also drizzled in some clear resin. Coasters are a great size to experiment with different techniques!

Once you’re finished working on it, cover it and leave it to cure overnight. After the epoxy resin is cured you can pull the silicone mold away from it. Now you have your cast Unicorn Glitter Epoxy Resin Coaster!

To clean up, I let everything with resin on it sit overnight. Then, once it is cured, I throw away all the little cups and popsicle sticks. But I keep the big mixing cups, because I can usually pop the cured resin out of the bottom. That way I have less waste.
