Using our SiLIcon Moulds with Metal Clays & Polymer Clays

There are 2 methods for using the moulds – Removing before drying and Drying in the moulds.

If you are using the moulds for Polymer Clay then please follow the instructions for – Removing before drying.

To remove before the clay has dried:

  • Use a release agent of your choice to coat the surface of the mould to be used.

  • Press the clay into the mould. You should press the clay down and out toward the side of the mould. Use an acryLIc roller to roll over the clay to even out the thickness.

  • Turn the mould to release the impression.

  • Trim & shape. Use a craft knife or similar to cut away any excess clay from the pattern.

  • If using metal clays then dry and fire as appropriate.

  • For Polymer Clays, bake in the oven as per the manufacturers instructions



  • To dry the clay in the mould:
  • For this method you do not need to use a release agent.

  • Press the clay into the mould using your fingers. You should press the clay down and out toward the side of the mould. Use an acryLIc roller to roll over the clay to even out the thickness.

  • To ensure that the back of the mould will be flat & even you can scrape away any excess with the side of a plastic spacer. Also remove any excess from outside the design.

  • Place mould on a flat baking sheet & dry in a moderate oven (150 to 180°C) for 20 to 40 mins. The time would depend on the thickness of the piece, or air dry naturally

  • Remove from oven and cool. Once cool to the touch turn mould over to release the impression.

  • Sand, file or carve as needed.

  • If using metal clays then fire as per the manufacturers instructions.


    Our moulds are made from very good quaLIty siLIcon and should last for a very long time. To clean the moulds just wash with a very mild detergent and dry. Do not use wash in a dishwasher or use any sharp objects to remove clay or dirt from the moulds.
