In today's video we feature a mold made of a Crazy Bone. A Toy based on an ancient Greece and Rome game called Knucklebones where children used sheep's knucklebones. Crazy Bones is a game, played with characters instead of sheep’s knucklebones. The game is played by lining up your crazy bones and your opponent lining up his/hers.  The first player chooses a Crazy Bone to flick at their opponents line up to knock down as many as possible. When a players Crazy Bones have all been knocked over, that person loses the game.

The mold was made using ComposiMold, we then poured Clear Casting Plastic into the mold and placed a tiny plastic man inside the liquid Clear Casting Plastic.

Turn a Glass Swan Into a Plastic Swan with ComposiMold

In today's project we used a glass swan figurine to make our own plastic figurine by using Clear Casting Plastic and a ComposiMold mold. Clear Casting Plastic is our jewelry grade, epoxy resin, that looks just like glass when it's cured. It is super easy to use too! Simply, mix Part A and Part B in equal proportions, by weight or volume, and pour it into your ComposiMold mold.


The supplies used for this project were:
ComposiMold-Original
Vegetable Oil Mold Release
Bubble Buster
Clear Casting Plastic our awesome Epoxy Resin
and a glass figurine of a swan

Remember: Thoroughly mixing this Epoxy Resin is very important. Be sure to scrape the sides of the cup to incorporate ALL material. Pouring slowly into your mold also decreases likelihood of bubbles forming in your final piece.

Be creative and tell us what you're up to! ~The ComposiMold Team

How to Use Epoxy for Mold Making and Casting

Epoxy is a plastic casting material. It begins as a liquid but becomes hard over time by curing.
Typically epoxy is a two parts mixture: Part one is the resin and Part two is the hardener. Epoxy works excellent as a casting material, and it  is also used for composite structures such as aircraft, surf boards, fishing lures, and some building work.

The advantages of epoxy include strength and ease of use. Most epoxy casting material for home or small scale use cure at room temperature and most epoxies are simple equal part mixtures by weight or volume, and unlike urethanes, most epoxies work very well as a casting material when small amounts of water is present.

To start casting with epoxy, the first step is to make a mold. There are a variety of mold making materials available on the market including silicone, latex, and wax based products, and if you are new to mold making and casting, using a reusable mold making material will enable experimentation and reduce costs and frustrations.

Because epoxies are versatile, a variety of mold release material can be used to ensure that the epoxy cast does not stick to the mold. Vegetable oil, mineral oil, or soap work effectively for small scale
productions, but for larger scale productions or composite work, mold releases made specifically for epoxy are recommended.

Mix the two parts of epoxy together completely by stirring. After mixing thoroughly, pour the epoxy mixture into the mold and let stand until solidified.

Filler materials are used with epoxy to give the cast a different appearance and properties. To make a stronger cast, glass fiber fillers of up to a quarter inch long are used. To give the mold a unique appearance or to take up space, talcum powder, wood sawdust, sand, or many other materials are used.

Epoxy is a versatile casting material that will enable you to create your own unique products and castings from your molds. To learn more about mold making and casting with epoxy, visit www.ComposiMold.com

Mold Release for Molds and Casts


Mold Release for Molds and Casts

1. Applying a mold release to your original object will allow it to be easily separated from the ComposiMold. 2. Applying a mold release to the mold before casting will also minimizes wear and tear on the mold. This is important if you are using the mold to make many reproductions.


Mold Release Bubble Buster


Applying Mold Release to your Original Object When Making Your Mold:

Mold Release

  • Spray a light mist coating of Mold Release over the entire surface of the original object and all surfaces of your mold box (and any surface that will come in contact with the ComposiMold). You can also use a clean paint brush or cloth to apply the mold release. Make sure that intricate details, undercuts and hard to reach areas are coated as thoroughly as possible.



  • Wipe off any excess mold release to make sure you do not have too much.


  • Bubble Buster
  • Spray a thorough coating of our Bubble Buster to your original object over the mold release. Make sure that intricate details, undercuts and hard to reach areas are coated as thoroughly as possible. Bubble Buster is useful when making your mold as it reduces bubble formation in the ComposiMold.



  • Continue with your mold making process by pouring the melted ComposiMold over your original object. See the basic instructions on our How it Works Page.


  • Applying Mold Release to your ComposiMold When Making Your Casts:


  • Spray a light mist coating into the entire cavity of your ComposiMold. You can also use a clean paint brush or cloth to brush the release agent into the cavity of the mold. Make sure that intricate details, undercuts and hard to reach areas are coated as thoroughly as possible.



  • Continue with your casting process by pouring or pushing your casting material into your mold per product instructions. See the basic instructions on our How it Works Page.


  • Do you need a special mold release when molding with ComposiMold?

    We sell a Silicone Mold Release that works well for mold making and casting, but many other mold releases also work well. Vegetable oil as a mold release is a perfect food safe option.

    Try these options as a mold release as well:


  • Petroleum jelly (Vaseline)


  • Cooking Spray


  • Mineral Oil


  • Soap


  • Motor Oil


  • Spray Lubricants (WD40, ArmorAll)

  • The best bet for determining the effectiveness of a specific mold release is to experiment. With ComposiMold you can!

    What do you do if you have bubbles forming in your mold? Or the purpose of Bubble Buster.


    In a nutshell, Bubble Buster busts bubbles. Bubble buster is a PVA/water solution that reduces the ability for the bubbles to stay on the surface of your master (original) when you are making a mold with ComposiMold or PowerMold.
    To see it in action, place a rock or other object in a glass of hot water and let it sit for a while. At some point, bubbles should form on the surface because the air in the water is coming out of solution.  
    Now spray the rock or other object with Bubble Buster or use a solution of water and PVA glue. The bubbles will not (or at least should not!) form on the rock.
    Do that with ComposiMold and you will have great molds with no bubbles.
    Thank you!
