How to make geode resin coastersIf you’ve been wondering how to make geode resin art coasters, then you are going to love this!  I’m going to show you, not one, BUT TWO ways to make the coasters everyone is talking about!  And the best part, they make great gifts!  Whether you need something for a man cave or a fancy living room, geode art resin coasters can be the center of attention!

Option 1:  Closed center resin geode

Step 1:  Gather resin supplies

To make this geode coaster, you will need:

Resin Obsession super clear resin
Silicone geode coaster mold
Mold release
– Resin colors.  I’m using Resin Obsession opaque white, Alumidust bronze and bronze colored glitter
– Rocks.  I like to use the ones meant for vases to hold silk flower arrangements.
Mixing supplies

Step 2:  Apply mold release

Apply a light mist of mold release to your mold surface.  Then, let dry for at least 30 minutes before adding resin.

Step 3:  Measure and mix the resin

You need to mix enough resin to fill the mold completely.  This article explains how much resin to mix based upon the size of this mold.

Step 4:  Mix resin and hardener together

When you first mix the two parts together, you will notice swirls and cloudiness.

Keep stirring!  You want the streaks to be gone and the mix to be clear.

Step 5:  Color the resin

Split the resin so you have about 1/2 to 1 ounce of mixed resin for each color, also leaving some clear.

Pro tip:  The white resin blends easily with the other colors.  Mix more than you think you need.

Step 6:  Add colored resin

Quickly pour white resin around the perimeter of the mold.

Then, pour colored resin next to the white resin.  Pour as many rings of colored resin as you want, being sure to work quickly. The resin will blend together at the edges.

Finish the coaster by adding clear resin and glass chips to the center.

Step 7:  Remove bubbles

Use a heat gun to go over the resin surface to remove bubbles.  Then, set aside to cure for 12 hours or more.

Step 8:  Demold

Once the resin is fully dry, peel the mold away from the geode coaster.  Sand up any rough images so that your coaster doesn’t scratch a table surface.

Step 9:  Finish the edge

To give your coaster a polished look, finish the edge with paint.  I used an acrylic bronze color.

Option 2:  Open center geode mold

Step 1:  Gather resin supplies

Follow steps 2 through 4 above for prepping your mold, measuring, and mixing the resin.

You will want to use the same steps as above.  Pour the resin quickly in rings starting from the outer edge of the mold, starting with the white.

Step 8:  Demold

I love how both of these coasters have a different look to them.

The good news is that they both hold a beverage bottle just fine.
