However, I do use a release agent.Thanks for the reply, I am new to glass casting. Just to be clear my question re using melamine sheet was specific to epoxy resin. I am considering using melamine covered MDF to use as a 'flat' mould, I assume from your reply this is ok! See image for what I'm doing.

For a high-gloss finish and ease of application, I would recommend 3-4 coats of a Mould Release Wax such as the Meguiar's #8 that we sell through Easy Composites. This will create a physical barrier on the surface of the melamine and, unlike PVA Release Agent, retain the high gloss appearance.If you were looking at series production, EasyLease could be considered but I'm guessing this is likely a one-off and so the wax will be perfectly fine.
