Have you seen the resin crafts with dots and drops of color in epoxy? You know–those ones that look like rainbows and clouds are growing in the resin? That’s a resin petri.
Less gross than the petri dishes you find in a lab somewhere.
How do you make a resin petri?
I’m so glad you asked.
Grab these resin supplies:
Step 1: Mix resin
The super clear resin is a great choice for petri projects. It releases bubbles easily and cures hard like glass.
Step 2: Pour into the mold
Add your clear epoxy to the mold.
Your stirring stick can help you get resin in specific spots too.
💡 Pro tip: Don’t overfill the cavities. You need room to drop in your alcohol colors.
Step 3: Add the alcohol tints
Pick complementary colors of alcohol tints. These tints are the only colors I’ll use for my epoxy projects. Because they’re designed for resin, they won’t fade or change colors as other brands can.
💡 Pro tip: Your colors are going to blend some. Be sure you use ones you like, even when the colors mix.
Next, add white alcohol ink on top. Continue alternating layers of colored ink and white ink for three to four layers.
Once the mold is full, allow it to cure. The colors will continue to blend to create some neat resin petri effects.
Step 4: Demold
Once the resin cures, peel the epoxy from the mold.
💡 Pro tip: Alcohol inks add extra moisture to resin which can make it cure bendy. Give your resin an extra few days to cure, especially if it’s a thin pour.
Once your resin petri earrings are cured, use wet/dry sandpaper to sand off the sharp edges on the back.
💡 Pro tip: It’s normal for the open side during casting to cure with a resin edge.
Step 5: Finish
I love my group of resin petri earrings. But, I can’t decide which shapes and color combinations are my favorite.
These are pretty cute. There are a lot of colors, making these easy to wear with almost anything.
Then I see the purple and blue resin petri earrings and think those might be my favorite. Or perhaps the little dainty blue and emerald ones are.
Then again, there are the blue and emerald dangles and the petite red resin petri earrings. Good thing I have lots of choices because I can’t decide.
And if videos are your thing, that’s cool. I love making them.
