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.

What Are Silicone Clay Molds?

Silicone molds for clay are a great way to create detailed designs using polymer clay. After working and conditioning your clay, you can fill the silicone mold with it, ensuring you get the material into every crevice. Typically, you will want to add extra clay to ensure you fill the entire mold. Once you are sure every space has clay, you can remove the excess from the back of the mold using a blade.

One fun benefit of silicone clay molds is you can bake the clay right in the mold for an easy and beautiful design! To remove the clay from the mold, you will want to set the form aside for a few minutes, allowing the material to slightly firm up. 

You can then gently flex the clay mold to remove the design. After unmolding your design, you can leave it as it is or add it to a larger project. Regardless of what you decide, whenever you are finished with your mold, you can bake your piece as you would any project involving polymer clay!

Benefits of Silicone Molds for Clay

Silicone molds for polymer clay continue to grow in popularity because of their many advantages and unique attributes. While each silicone mold offers various special features, some of the most popular benefits of these products include:

  • Easy to use: One of the best things about silicone molds for polymer clay is they are incredibly easy to use. You can make a highly detailed piece for your project in just a few minutes. Even children can use these molds for their projects, as long as an adult is present when helping to remove excess clay with a blade.
  • Versatile: Silicone molds are helpful for creating a range of items, from earrings and paperweights to figurines. You can also use these molds to add unique designs and intricate details to a larger figurine, statue or project.
  • Non-stick: Because of their composition, silicone molds are naturally non-stick, making it easier to fully remove the finished piece from the mold.
  • Durable: Silicone molds are strong, ensuring they last a long time for your future creations. Even if a silicone mold gets bent or compressed, it will still retain its shape.
  • Ideal for mixed media: If you are working on a mixed media project, you can use silicone molds with polymer clay, resin and more to create a detailed and eye-catching piece.

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 polymer clay parts 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 blade.
  • Shave off extra clay with your blade one more time after refining the edges of your mold with a blade or other 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 that you can bake your clay right in the mold. Simply place the mold with clay in the oven and bake per the clay's instructions. 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 it 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.
