Methods of operation of an induction melter are disclosed. Particularly, a cooled crucible and an inductor may be provided proximate thereto for heating at least one material therein. A desired electromagnetic flux skin depth for heating the at least one material within the crucible may be selected and a frequency of an alternating current for energizing the inductor therewith and for producing the desired skin depth may be selected. The inductor may be energized with the alternating current having the selected frequency. Optionally, the frequency of the alternating current may be selected in response to a difference between a desired skin depth and the indicated skin depth. The desired skin depth may be selected to be about 38% of a diameter of the at least one material. The desired skin depth may be substantially maintained as the temperature of the at least one material varies.
