ABSTRACT:
An apparatus for melting samples in crucibles above burners while moving the crucibles to mix the contents. The crucibles are supported by movable shafts on a movable subframe. The shafts can oscillate in a horizontal plane to mix the contents of the crucible. The subframe can also oscillate vertically to mix the contents of the crucible. The crucible mixing pattern is the sum of the horizontal and the vertical motion applied to the crucible. The crucible can be moved back away from the burner to add additional material to the crucible. The crucible can be moved forward, away from the burner, to pour the melted sample into either a heated casting dish or a container containing a solution. Nothing is added to or poured from the crucible while over the burners.
