Seashell resin magnets – turn seashells into refrigerator magnets

How to make seashell and resin magnetsI spent a couple of days with my peeps at the beach.  While we were there, they amassed a small collection of seashells and sand to take home.  I talked them into making a few mementos of our trip that we could display on our refrigerator as seashell resin magnets.

Step 1:  Dry the sand

Before you use your shells and sand, you want to make sure they are absolutely dry.  I put mine in a 150-degree oven for 1 hour.

If your sand isn’t dry, that extra moisture can affect curing and keep resin sticky.

Step 2:  Place on a drying mat

Once the shells and sand were cool to touch, I arranged the shells on a drying mat.  I used the mat because I wanted to make sure the shells rested flat.  The mat openings and knobs will help keep them in place.

The other thing I love about this drying mat is that you can peel resin off of it once it’s partially cured.  No more drips stuck to my crafting table!

Step 3:  Mix resin and add to the shells

Mix your craft resin according to label directions.  Spoon a small amount of the resin into each shell.

Step 4:  Add the sand

Put a little bit of sand into each resin-filled shell.  The sand will sink to the bottom of the shell.

Step 5:  Mix the sand and resin together

Mix the sand with the resin to evenly cover the bottom.  Check for bubbles, then cover and allow to cure.

Step 6:  Add a magnet

To make these into seashell resin magnets, they need a magnet applied to the back.  I used E-6000 glue to adhere a rare Earth magnet.  Allow curing for 24 hours before using it.

  1. is there any way that you might be able to post a pic of the necklace with the washer? would love to see it cause I cannot get a Visual on what it would look like ..thank you …Kathy Howington….

  2. How did you keep the sand intact? I’ve been making resin jewelry with beach sand mixed in for awhile, and I make sure the sand is dry before I use it, but the resin pretty much dissolves it. The only thing visible is the impurities- the sand itself completely disappears 🙁

  3. @Stevieretro,

    All I did for this tutorial was to add beach and until the resin was almost full. The sand will settle to the bottom. If yours looks like it’s settling out, I would suggest either adding more sand or coarser sand.

  4. Hi I was making some shell tiles and used a little sand to put around the shell, the sand just floated around and eventually sunk but looked bad.

    Right now I am making another shell tile (to be a pendant) using small shells. I notice that the one’s that are rounded float, I pressed them down with a toothpick but I think I might have made the pendant (tile) bumpy and it will not be smooth. This is suppose to be a gift. How can I make them not float?

  5. @Bonnie,

    Try dipping some of the smaller shells in resin first, then allowing to cure on wax paper. Once cured, peel them off and add to your next casting. The extra weight of the cured resin is usually enough to keep them from floating.

  6. I usually use sand in my bezels as a backdrop. I find that if I spread a little resin in the bezel and pour the sand on top, it works great. I let it cure and then add a few shells and sea glaass and add more resin. They turn out really nice

  7. I want to make a pendant using soil from land in Africa- does soil follow the same principles as using sand? Is there something I should do differently?

  8. Hi Katherine, I have glass jars, vases, glasses all shapes n sizes. I’m putting sand in bottom, arranging shells and beads, gems, crystals on top. What can I use that dries clear, keeps the sparkles alive and pieces in place? My idea was to have something I can pour or spray into glass just covering enough to seal a top layer ( about 1/8 inch) so it doesn’t spill, keeping design in place. I thought spray acrylic, but would it hold shells and sand in place? Or a resin?

  9. I love shells! I have a variety of shells of all sizes and several sizes of starfish. I made a necklace and earrings by coloring part of the inside of the 3/4″ and 1″ clam shells a pale aquamarine shade for sea and very fine sand mixed with modpodge for shore. When it was dry, I sprayed them with acrylic laquer and glued small pearl beads and tiny starfish on them, to make a “sea scene”, like little shadowboxes. I get lots of comments whenever I wear them. I tried using resin at first, but it just didn’t look right.
