When casting with metal in rubber moulds it is essential you apply a layer of our release agent on both sides of the open mould. This allows for air to escape and stops the mould sticking together. Do not apply too much as you don't want it to block the flow of metal. Clap the two halves of the mould sharply together a few times to knock off excess powder. If you are casting many times, you may wish to wipe off the old powder from previous applications and apply a fresh coat.
