Are you wondering how to use silicone molds with polymer clay to get a good casting? Read on for tips and tricks for making polymer clay designs with silicone molds for a fun, easy and mess-free project.

How to Use Silicone Molds With Polymer Clay

Due to their ease of use and flexibility, silicone molds are a popular choice for working with polymer clay. You can make molds from plaster, silicone or a variety of other materials. One benefit of working with rubber silicone molds is that they are naturally non-stick. 

If you don’t want seam lines, we recommend kneading your polymer clay before pressing it into your mold. To get a quality cast, try these tips:

  • – Fill the silicone mold with little pieces of clay at a time. Be sure to push down the polymer clay into the smallest crevices of the mold.

  • – Continue to add more clay to the silicone mold until the entire area is filled.

  • – Once you’ve filled all the empty spaces of the mold with clay, press down with your fingers to ensure all pieces of the clay are melded into the silicone mold. If any parts of the polymer clay come out of the mold, press them firmly back down.

  • – Use a blade to slice off any last bits of clay carefully. 

  • – To clean up any areas where the clay spills over the mold’s edges, try using a needle tool.

  • – Shave off extra clay with your blade one more time after refining the edges of your mold with the needle tool.

  • – Make sure the face of the silicone mold is free of excess bits of polymer clay.

Tips on How to Get Polymer Clay out of a Silicone Mold

Many silicone molds can be baked in the oven so you can bake your clay right in the mold. If you purchased a mold, check the packaging or with the seller before baking your polymer clay.

If you are not baking in the mold, here are tips on how to remove your polymer clay. To remove clay that does not have many fine ridges or protrusions, turn it upside down and flex the silicone mold. Some tricks to remove clay that does have fine projections include:

  • Use a piece of transparent plastic sheet that’s been cut from a sheet protector. Smooth it onto the clay to ensure it adheres properly. Then, turn upside down and try to flex the mold again. 
  • For a more vigorous method, get a clean piece of glass or ceramic tile. Then, invert the mold onto the tile and press down firmly on the mold. Once the clay has adhered to the tile, lift the edge of the mold and flex it as you pull it off.
