High Temprature Dry Release Agent, apply a thorough coat and then allow to dry for 5 minutes, then follow with a second coat and you are ready to go. Top up coat(s) can be applied as neccessary according to firing temperature and frequency. With a casting mould a top up coating may be required each time due to higher temperatures. It will allow a clean realease without spines and sharp edges.
