The improved crucible of the present invention both filters molten metal during the transfer of the molten metal from a supply receptacle such as a melting furnace to a receiving receptacle such as a mold. The transfer crucible of the present invention may be either portable or permanently mounted. The present invention relates to both the design of the improved transfer crucible and to the method for using the improved transfer crucible. The transfer crucible of the present invention is fitted with one or more removable blades, each of which contains a filter element. Molten metal can be filtered while the crucible is being filled with molten metal, during transfer of molten metal, or if desired molten metal can be filtered both on entry into and on exit from the transfer crucible.
