How to make a silicone mold for resin or polymer clay

Did you know you can easily make your own silicone molds with the two part silicone mold putty kit by Alumilite?  This video, courtesy of Meredith of Cosmic Designs shows you how to make a simple silicone mold ready to use in 30 minutes.  (And by the way, this silicone is food grade safe, so you can make some neat ice cubes or chocolate treats as well!)

I learned a new technique from you. Your mold is really good. I like how you drop your putty ontop of your item. I was going the wrong way.


I was going the other way too! I must try it your way, looks like you will get a better impression and mold… Thanks so much for sharing


I really like how you did this but is there a way to make a mold of something you dont physically have? I want to make Kida’s necklace from Disney’s Atlantis only I dont have the physical shape of the crystal to mold with. How should I go about it?



You can’t make a mold of something without a physical model. What I would recommend in this case is to find a wax carver (we can hook you up with one) to carve a model for you. You can then make a silicone mold from this wax model.


Cam – It’s totally possible to make a mold without having a physical object. All you need is a 3D modeling program like Maya or Zbrush for your computer and enough skill in using it to create a 3D render of the object. Considering the simplicity of the crystal, it should only take about 30 minutes. Once the 3D render is complete, invert it. Then send the file to a place like Shapeways that does 3D printing. You can have a perfectly detailed mold delivered to you and ready for use within a couple days.
