Yes, but the method for making sure the material separates from the plaster mould is quite involved. Some mould makers use shellac, followed by a soap treatment. There are several steps to the process, and you will probably have to destroy the mould as you break the positive out. For detailed steps on how to do this, research "plaster waste moulds"
