ABSTRACT:
An apparatus for casting a fusible material has a support on which is provided a row of melting burners and a parallel row of warming burners. A crucible holder on the support has a pair of bars forming a plurality of seats each above a respective one of the melting burners and each for a respective crucible. A slide having a plurality of mold holders is displaceable into a position with the mold holders above the warming burners. Once the material in the crucible holders has been melted by the melting burners the entire crucible-holding assembly may be agitated horizontally to homogenize this material. Thereafter the entire crucible-holding assembly is tipped up to pour the contents of the crucibles into the molds which have been preheated by the warming burners. The warming burners are then shut off and jets of compressed ambient-temperature gas are directed at the molds to cool the material therein and solidify same into a tablet or slug suitable for X-ray analysis.
