Thermochromic (Color-Changing) Resin Bracelet & Ring Set

Use the magic of thermochromic (color-changing) powder and resin to make an eye-catching bracelet & ring set!

Thermochromic (Color-Changing) Resin Bracelet & Ring Set

Resin is one of my favorite crafting materials. If you're a beginner, jewelry is something simple thing to start with, and is a great go-to gift idea. Not only is this resin bracelet & ring set quite the statement, but it has a fun color-changing twist. Like a mood ring, this set uses the magic of thermochromic (color-changing) powders to change color with heat!! I love how this set turned out, and am excited to show you how you can make a set for yourself!

What makes this project so magical is the thermochromic powder! There are 5 different heat-sensitive color changing powders in this set, but I went with just three for this project: purple-pink, dark green-lime, and violet-blue.

Pout down a silicone mat to protect your workspace. Prepare 2 oz. of EasyCast Clear Casting Epoxy according to package directions. Stir the resin mixture together with a stir stick for two minutes, making sure to scrape the bottom and sides of the mixing cup. After 2 minutes, pour the resin into a clean mixing cup and stir the resin again for another minute or two with a clean stir stick.

If the resin mixture is still cloudy or streaky, you will need to keep stirring until it becomes clear. To keep the bubbles down to a minimum, don’t stir too fast, and give the resin a minute or two to “rest” after mixing to let any bubbles rise to the top.

Arrange the bracelet and ring molds onto your silicone mat. Split the resin into three smaller mixing cups. Use the small spoons (included) to add thermochromic powder into each cup. Stir the resin mixtures slowly until the powder is completely combined with the resin. If you want the colors to be more vibrant, add some more powder and mix completely.

Once resin has been mixed, it starts to heat up as a chemical reaction. Normally you may not notice, but with thermochromic powder, you sure will! Check out the colors in the mixing cups - the colors have changed to lime green, hot pink, and bright blue!! Isn't that awesome?!

Use droppers or your stir sticks to add a little bit of each resin mixture into the bracelet and ring molds until the mold is full. To prevent a lot of trimming later, make sure not to overfill the molds! Let the resin sit for a few minutes, then use a straw, heat gun, or spritz with 91% alcohol to remove any air bubbles that rise to the top.

Leave the resin to cure in an undisturbed, well ventilated area for 24 hours. You will know that the resin is completely cured when it is no longer tacky to the touch. As the resin cures and cools down, you can see the resin change back to dark green, violet/dark blue, and purple/magenta. It's such a fun process!

“Demolding” (removing resin from a mold) is one of my favorite steps when working with resin. My projects are usually made “upside-down”, so the big reveal so exciting! Carefully remove the bracelet and ring from their molds. If you are having trouble getting the pieces out, you can add a little bit of water into the mold and they should slip right out.

If you have any over-poured resin, you can trim the excess away using a craft knife or scissors. Rougher edges can be sanded them down with a fine grit sandpaper. If the resin still feels flexible, it may just need more time to cure. Make sure they are in the right shape and let the pieces sit in a warm, flat area to cure for a few hours (or days).

Ready for this?! When heated up to 88º F (31º C), the resin magically color-changes from the darker shades to these brilliant and vibrant ones! I am beyond impressed with the thermochromic powder, and think making jewelry is the perfect use for it.

The ring fits perfectly on my pointer finger, and love how the bracelet fits on my arm. These pieces of jewelry are certainly statement pieces. Once they start color-changing, they will also become a conversation piece! The ring color-changes pretty quickly with body heat, but the bracelet takes a bit longer because it's a bit thicker.

I am absolutely enamored with this project, and am so excited to be sharing it with all of you! This is such a fun resin project, and I definitely recommend that you grab some thermochromic powder and bracelet and ring molds to give this project a try!
