When I was younger, one of my favorite things to do at the beach was to find sea glass. Sea glass is the remains of broken bottles and jars that make their way into the ocean. After weeks to months of tumbling in the water and sand, they come back to shore with a soft and frosted finish. I remember collecting jars of the stuff. If you don’t have a beach nearby, don’t worry. Today, I’m going to show you how to make your own sea glass with resin.
You’re going to need these resin supplies:
- Resin Obsession Super Clear Resin
- Castin’ Craft mold release and conditioner
- Resin mold with round cavities of varying sizes, about one-half to 1-inch wide
- Reusable measuring cup
- Stirring Sticks
- Disposable Spoon (optional)
- Crystal microglitter
- Resin Obsession transparent green pigment
- Rolling pin
- Silicone mat
STEP 1: Prep the mold
Spray the mold with the Castin’ Craft mold release and conditioner, and leave it to dry for at least 30 minutes.
STEP 2: Measure and mix the resin
Measure 1 ounce of Part A resin and 1/2 ounce of Part B hardener of your resin for crafts into separate cups. Mix them together until clear and streak-free.
STEP 3: Color the resin
Drop a small amount of transparent pigment into the mix until it’s the color you want. Then, add a pinch of microglitter and combine. This is the secret to the realistic sea glass look.
Pro tip: Search images of sea glass and keep them nearby while you add the epoxy color. This will help you get realistic-looking glass.
STEP 4: Add to the mold
Pour the mixture into the mold until half-full. Then and leave to partially set. For the super clear resin, this takes about 1 to 2 hours.
Pro tip: If you are using a different epoxy resin, you will need to watch your resin for the partially set phase.
STEP 5: Remove the resin from the mold
You’re ready to work the resin when the surface is no longer a liquid, but you can dent it.
Pull the resin out of the mold with a blunt object (you can use a resin stirring stick so as not to damage your mold). You can pick off any extra bits left inside after the resin hardens completely.
STEP 6: Shape the resin
Here’s the core step of how to make sea glass with resin so it looks like real sea glass. Tear the resin into pieces to make sea glass for small jewelry or crafts. For a decent-sized pendant, leave the blob whole. Shape the resin roughly with your hands and put it on a non-stick mat.
Don’t worry about fingerprints. This will frost the surface, which is a good thing for realism. Most of the fingerprints will disappear once the resin fully cures.
Use a rolling pin to lightly squish the piece of resin to mimic the thickness of old glass.
Important: If you’re using a rolling pin from your kitchen, don’t use it for food again. Otherwise, you can use a piece of PVC pipe for this step.
STEP 7: Finish curing
Leave the resin to set for at least 4-5 hours. Then, you are free to drill the resin charms and do as you wish with your faux sea glass.
