How to make resin magnets

Have you ever needed just a small gift for someone.  Nothing elaborate or even expensive but just a little something to express a feeling.  Maybe a thank you to a neighbor who helped you plow snow.  Maybe a stocking stuffer or secret Santa gift.  Or maybe just a small gift to say I’m thinking about you.  Magnets can make a really nice little gift for these occasions.  In this tutuorial I’m going to show you how to make magnets using epoxy resin.  

So let’s get started!

Epoxy Resin (I use Art Resin for this type of project)
Color Shift Mica Powder
Royal Blue Mica Powder
Craft/Stir Sticks
Silicone Mold (Mine is a heart silicone mold)
Black Acrylic Paint
Two cups for the resin/hardener
Hobby Magnets
Gloves (preferably Nitrite)

Mixing Resin

When I mix my 2 part epoxy resin I first label the cups with an H for hardener and an R for resin.  This way I can reuse these cups.  I then put hardener in one cup and resin in the other in equal amounts.  It must be in equal amounts.  That being said, I do just eyeball it in the cups.  I have never had a problem doing this.  

Then I pour the resin and hardener into one larger cup.  Be sure to scrape each cup out well, again, you want it to be equal amounts.  Begin to stir the resin and be sure to scrape the resin off the sides as you stir it.

At first when you add the resin to the larger cup, you will notice it is nice and clear.  But as you start mixing the resin it will begin to get cloudy.  Don’t fret over this, that is normal.  Just continue to mix and it will clear up again.  Try not to mix too vigorously as that can create a lot of bubbles and you don’t really want too many bubbles if you can avoid it.  You can limit the amount of bubbles by putting your cup in a warm water bath while you mix it.  I didn’t do that for this tutorial.  In my tutorial on “How to Resin Glass Table Tops” you can see I did use a warm water bath.  Feel free to check out that post.

Blue Glitter

I will be using blue glitter for the first set of magnets.  I typically create magnets in sets of three.  This is just my own preference.  I feel three refrigerator magnets makes for a really nice small gift for someone.  

First I pour some resin into a small plastic cup.  I will usually just eyeball the amount.  In this case, enough to fill three of the the silicone heart molds.  Add the glitter, stir, and pour it into each of the molds.  Here is a short video of the process.

Color Shift Mica Powder

When I was learning how to make magnets, this became one of my favorites.  Color shift mica powder really is fantastic.  I can’t say enough about it.  There is a process in using it for this purpose.  I’m no color shift expert but my experience has been as follows.  One must first put a layer of the color shift mica powder onto the mold with a paint brush.  In order for it to come out looking its best it needs to have black “behind” it.  That is where the black acrylic paint comes in.  I have tried mixing the color shift mica powder right into the resin and that did not work well.  Here is a short video to show you how I did it.

Royal Blue Mica Powder

Using this mica powder one doesn’t need to have that painted layer on first.  I just mix some into the resin.  This royal blue mica powder is my favorite color and one of the first mica powders I purchased.  Here is a short video to show how I did it.  

Now we wait!

Now that all of the silicone heart molds are filled we will need to wait for the resin to cure to add the magnets.

Twelve hours later

At about the 12 hour mark the resin will be cured enough for me to add the magnets to the back.  So in this short video you will see me doing just that.  I used Diamond Glaze  to secure the magnet onto the heart.

Removing magnets from the mold

Once the Diamond Glaze has hardened the magnets are ready to go on the refrigerator. 

In Conclusion

In this tutorial I showed you how to make magnets using  mica powder and glitter.  These magnets can be given as gifts for any occasion.  I hope you enjoyed learning about this process.  If you have any questions or would like to let me know of other projects you would like to see, let me know in the comments below.  And follow me on Pinterest and Instagram to see some of my other beautiful creations.  

Fun Fact!

You can increase the life span of a silicone resin mold by spreading a very thin layer of coconut oil in it before or after using it.

    • Hi Heidi, I order many of my supplies directly through Amazon. They are called craft magnets or hobby magnets.
      I don’t have a preferred brand necessarily.

      Thank you for checking out my site, great question.
      All the best,

  1. Hi Teresa,

    I love this article and I love your site. I have been looking for different things that I could do with my niece for fun, and she would love to make refrigerator magnets. She could make them for her grandparents, parents, and friends.

    I have also forwarded your article onto my friends who have small children who could also have a lot of fun.

    Thank you for sharing and keep up the great work.

    All the best,


    • Hi Tom, thank you so much for your kind words and for visiting my site. I’m really glad you can
      see how magnets can make such a nice little gift for someone like you mention. That’s excellent.
      I hope you’ll try it I wish you the best,
      Thank you again,

  2. That was a great tutorial, thank you! I love crafting, in every possible form. I love creative people, especially those who are willing to share the knowledge, as you are. Your style “fits” me and I like the little advices, like the one about marking the glasses for reuse or the one about avoiding the bubbles! Also, I did not know it can be mixed with a simple acrylic paint, so I’ve learnt something new today. Resin have been for a long time on my mind, but I never actually started using it. I do have a collection of ideas I’d like to bring some day to life with resin, though, so I’m bookmarking your site!

    • Hello and thank you so much for visiting my site. I’m super glad you were able to take some new
      knowledge from it. That’s great! Be careful, once you start it can be addicting. lol

      I wish you the best of luck,

    • Hi Brianna, No, for these magnets I did not use a UV light. This is a two part epoxy resin I used
      in this tutorial. UV resin uses the UV light for curing.

      Thank you for the question and for visiting my site.
      All the best,

  3. This is as fantastic activity to do with the kids, especially with them being at home so much now! Your fun fact is great, but I take it the coconut oil won’t affect the finish of the resin? Or is the certain way to clean the magnets to remove any oil residue, or is soap and water sufficient?

    • Hello Gareth, only a very small amount of the oil needs to be applied. It can be wiped off with a clean cloth
      and there still will be that bit of residue left from the coconut oil. That is enough to protect
      the silicone mold until after the next use.

      Thank you for your kind words and for your great question!
      All the best,
