1. A method comprising:
placing a material in a horizontally oriented vessel;
operating a first induction coil comprising a plurality of coil turns at least partially surrounding the vessel and defining a melt zone at a first RF frequency, thereby forming a molten material;
while operating the first induction coil, operating a second induction coil at least partially surrounding the vessel and positioned in line with the first induction coil at a second RF frequency that is different that the first RF frequency to contain the material within the melt zone; and
forming the molten material into a bulk metallic glass (BMG) part.
