Abstract
There is disclosed an improved method of melting a charge blank of an electrically-conductive fusible material including the steps of positioning at least one substantially ring-shaped charge blank in a crucible wherein the charge blank has an outside transverse dimension and height of about 1.1 to 10 and 0.8 to 3, respectively, times an inside transverse dimension thereof, and thereafter subjecting the charge blank to the electromagnetic field of an induction coil.
