Beschreibung
Zusammenfassung:	An apparatus for pouring a molten metal comprises a crucible having a bottom wall member with an aperture formed therethrough and an integrally formed ceramic molten metal dispenser. The ceramic molten metal dispenser includes an upstanding first tube positioned within said crucible and having a first end located around the aperture and another second end that is closed. The first tube has at least one entrance for allowing the passage of molten metal from the crucible to the first tube, and has a double wall to define a molten metal receiving cavity. An upstanding second tube is located within the first tube and having one end coupled to the first end of the first tube and in fluid communication with the aperture and another end defining an inlet from the first tube. A passageway extends along the second tube for the passage of the molten metal from the entrance to the inlet.
