To use:

• Fill both sides of the mould with wet metal clay, ensure the clay is pushed in all the way down into the shape. The mould is transparent so it makes it easy to check, simply turn it over and ensure it is completely filled and there are no air bubbles. Silicone moulds generally don't need any non-stick solution, however we always recommend using a little to make de-moulding easier. You can use CoolSlip, Badger Balm or Slik Baby before placing on the clay to avoid sticking.
• Leave to dry in the mould. Be patient with the drying! It takes longer than you think to dry in the mould, as the heat only gets in from the top. If you try to pull them out too soon, you'll wreck or distort the shape. We recommend drying for over 24 hours in a warm dry room. You can speed it up by putting the mould in a dehydrator.
• Once dry, gently push the pieces out of the mould, if you are creating a 3D shape take both sides and secure them together with some Art Clay Paste.
