10 Uncomfortable Truths About Resin Jewelry Molds

uncomfortable truths about resin jewelry moldsIf you’ve spent time on social scrolling for jewelry inspo, you’ve seen trends like bangle bracelets and boho chic earrings. If you want to make them too, you can. All it takes using resin jewelry molds.

But before jumping into making resin jewelry with molds, there are ten things you need to know first.

Truth 1: You can’t use any mold to make jewelry.

Have a stash of chocolate molds? Or maybe candle molds? Perhaps some soap molds?

You get the idea.

While I appreciate your desire to repurpose, you can’t use any plastic mold with resin. Why? Mixed resin can stick to non-resin plastic molds and damage them. Or not come out at all.

Don’t believe me? Here’s what happened when I poured epoxy resin into a soap mold. Spoiler: It wasn’t a happy ending.

⭐️ BONUS: Learn how to successfully use resin casting molds on your first try.

Truth 2: Resin molds for jewelry will eventually wear out.

Your molds aren’t going to last forever. How long your resin jewelry molds last comes down to either the number of times you’ve used it or how long you’ve had the mold.

Resin jewelry molds are only suitable for so many uses. Generally, silicone molds for resin last for 2 to 3 dozen castings. If you get more than that, consider yourself lucky.

The other problem is time. If you only use the mold a time or two, and then put it away, it will eventually dry rot. The mold becomes brittle and tears when you demold your resin.

⭐️ BONUS: Learn why resin sticks to silicone molds.

Truth 3: There’s a big price difference in resin jewelry molds.

There are different processes to make resin jewelry molds. Some methods press the mold material (silicone or plastic) onto a template. The other technique involves pouring liquid silicone around the template.

Poured molds will sell for more than pressed molds. More silicone molding material equals more cost.

The good news is that poured silicone resin jewelry molds last longer than pressed molds.

⭐️ BONUS: Here are silicone mold care tips to safeguard your investment.

Truth 4: Not all resin jewelry molds make shiny jewelry.

Unfortunately, resin beginners mess this one up a lot. You assume that because the mold is silicone, it must create a glossy surface.

Have you tried using silicone baking molds to make resin jewelry?

The surface comes out cloudy, and you blame it on your jewelry resin. Instead, the mold is what’s making the resin cloudy.

If you want a shiny surface for your resin, you must use a mold made from a shiny template. (which baking molds usually aren’t)

So how do you know if your mold will make shiny resin jewelry? Look at the mold cavities. If they’re shiny, your resin jewelry will be shiny too.

⭐️ BONUS: If your resin jewelry comes out frosty, here’s how to fix a cloudy resin surface.

Truth 5: Too much heat will damage resin molds for jewelry.

Resin gets hot. So shouldn’t the mold be able to handle the heat?

Of course. But that doesn’t mean you can torch it like you’re trying to get snakes out of your house. (Which sounds like a perfectly reasonable response to that situation.)

Keeping a heat gun in one place for too long can soften or warp a mold.

⭐️ BONUS: Here’s how to use a heat gun with resin molds.

Truth 6: Clear silicone molds cost more than colored silicone molds.

Clear silicone costs more, like leather seats versus cloth seats in a car.

So what makes clear silicone awesome (and why are they worth the extra price)? Because you can see what you’re doing in the molds when making resin jewelry. You can see exactly where to place flowers or annihilate bubbles before letting your epoxy resin cure.

⭐️ BONUS: And what do you do with those bubbles when you find them? Here are ten ways to get bubbles out of resin.

Truth 7: Resin mold release will prolong mold life.

Using mold release will protect your molds against micro-tears that wear them out. Ever had resin stuck to a mold and tear it? Mold release guards against that.

Plus, it makes your resin slip out so easily. Kinda like a pocketful of pudding.

⭐️ BONUS: Here are three reasons why I always use resin mold release.

Truth 8: Consider how you will use the jewelry molds before you add resin.

I’ll get right to an example on this one.

Here’s an alphabet mold. Seems pretty easy to use. Add resin and demold, right?

Except when you demold, you see that the shiny side of the resin letters is backward. That means when you use this mold, you must design ‘face up’, which isn’t how we ordinarily use resin molds.

What’s the problem with using resin molds face up? The surface will have a resin edge which you’ll have to remove.

⭐️ BONUS: Here’s how to handle a resin edge so you can wear your jewelry charms.

Truth 9: Not all resin molds demold easily.

Molds with skinny openings can be a b@#%h to demold. Scrape your knuckles a couple of times, and you’ll swear you’re never going to try clear casting resin again.

The good news is soapy water can be a lubricant and helps cured resin slide out of your mold.


⭐️ BONUS: Here’s my video showing how to do this.

Truth 10: Resin jewelry molds can warp.

You’re done with your mold. Now, what do you do with it? Once it’s clean, store it flat. Keeping it in a wonky position for an extended period can make it freeze that way. (Kinda like the face of the girls in that movie.)

Once it’s misshapen, it may not go flat again.

⭐️ BONUS: Before you put that mold away, make sure it’s clean.  Here’s how to get uncured resin off silicone.

Congratulations, resin creator. You’re ready to get started with resin jewelry molds!

  1. Question about filling a faceted bead mold–I have a bead mold similar to the European mold you have to sell. My mold does not have an opening at the top that is as big as the opening in your European mold. When I go to fill the mold with a pipette, the resin goes in and comes right back out. I understand it is probably air in the mold that is forcing the resin out, but how do I overcome that? The cured resin comes out easily but often I end up with a ball that is only 1/2 ball. Now I have lots of failed resin to be used somehow, and no round beads for a project I want to do.
