How to create Small Epoxy Castings with Fewer Bubbles using Liquid Diamonds

We will cover how to reduce bubbles in small epoxy castings with Liquid Diamonds & how to protect your Silicone Molds

Start with: 

 

Quick Video Demo Listed Below.

 

The secret & most crucial step to decreasing volume of bubbles in any pour is slowly adding part A to part B and slowly mixing them together without whipping air into the mix. 

 

Step 1: 


Measure 2 parts of resin and 1 part of hardener by volume. Mix together slowly for approximatley 5 minutes.

Slow and steady reduces bubble action.

Vigourous stirring leads to accidental whipping of bubbles into the mixture. Pay close attention and you can literally see bubbles being injected into the mixture the faster you stir. 

 

Step 2:

If you are adding color, complete the first 5 minute mixing session then add the colors. Again slowly mix the colors into the batch.

 

Step 3: 

We like to let the mixture sit for an additional minute to allow any bubbles we mixed in to rise to the top surface of the container.

 

Step 4: 

Use a mini torch (waving it 6-12 inches from epoxy) to release bubbles from the surface.

 

Step 5: 

Lightly spray the interior of the silicone mold with our Mold Release spray (waving 6-8 inches from mold).

After 20-30 seconds, the mold is ready to be poured into.

 

Step 6:

Slowly pour the Liquid Diamonds mixture into the mold. 

***Try slowly pouring a small amount and stop. Look for bubbles. Use the mini-torch. Pour again. Stop. Look for bubbles. Use the mini-torch. Repeat until completed. 

 

Step 7:

Monitor for final surface bubbles. 

Use a mini torch (waving 6-12 inches from epoxy) to release the bubbles from the surface again.

 

Step 8: 


Allow approximatley 24 hours to cure before touching. 

Gently test an edge of the project to see if dry to touch.

If dry, slowly pull the project out of the mold.

Because we treated the silicone mold with mold release, it should be much easier to release. 

This helps prevent unwanted rips and tears to the mold, ultimately lengthening its life span. 

 

Hope this has helped.

Next level, is investing in a vacum chamber. This eliminates bubbles. 

More on that in a future post.

As soon as I run out of the resin I’ve got now, I want to give the liquid diamonds stuff a try. I want to make clear little glitter skulls for halloween decorations.
p.s. Do you have any plans to have soft or gummy resins in your store in the future? I’ve been looking for some online and there aren’t a lot of options out there.

I’m looking forward to making more small jewelry items to give to my daughter to incorporate into her beadwork.

I really picked up a lot of great bubble-reducing tips in this article that I can’t wait to apply to my epoxy resin art! To answer your question, my dream project would be a galaxy coffee table like the one featured on your Facebook page, but in the meantime, I’ll use these tips to make pretty coasters and trays. Thank you so much!

Funny thing about epoxy is; epoxy is a never ending learning experience with a multitude of possibilities. Epoxy keeps the mind moving like liquid diamonds flowing through the soul.

As with a previous writer I can always learn something. After all someone who knows everything about everything can’t be taught anything about anything. I use a small heat gun instead of a small torch that way you don’t have an open flame to worry about. When I was in Canada I stopped in at a craft store called Michael’s and picked up a mold to make picture frames. I haven’t used it yet but looking forward to cadting dry flowers in it. If this works out i am going to keep doing it. I have 13 grandchildren

I’m starting out creating different things from coasters, trays and key chains. I would love to learn how to create the big pyramids with different things in them like the little lights and flowers. They are really beautiful.

I’m not so patient and don’t always follow the rules. I find your resin very forgiving when I forget and think I’m folding a cake batter. But thank you for the reminder!

As someone who makes and sells epoxy resin products, I would like to state that I really enjoyed your article. I hadn’t read a blog about epoxy in a long time, I thought I knew everything about it. Thank you.
