The apparatus comprises a vessel having an interior. A mold is disposed within the interior of the vessel. A casting material is contained in the interior of the vessel. The apparatus also comprises a mechanism for providing the casting material to the mold in a manner such that vapors of the casting material are prevented from communicating with the interior of the vessel. The providing mechanism is in communication with the vessel. The providing mechanism comprises an inner chamber within which the mold and casting material are contained in. The providing mechanism further comprises a mechanism for heating the inner chamber, such as heating coils. The heating mechanism is disposed within the interior of the vessel adjacent to the inner chamber. Preferably, the inner chamber has a tube extending therefrom having a filter element, disposed therein for catching vapors of the casting material. Preferably, the tube extends through the vessel such that the interior of the vessel and the inside of the inner chamber are fluidically isolated from each other.
