Claim 0:
1. A delivery orifice assembly for coupling to a submerged combustion melting apparatus, the delivery orifice assembly comprising:
a susceptor sleeve comprising walls and a sleeve end configured to receive a molten material;
a coil surrounding the susceptor sleeve, the coil being configured to:
inductively heat a volume within the susceptor sleeve; and
conductively cool the walls of the susceptor sleeve via a heat transfer fluid flowing within the coil;

an inner liner having a first refractory composition disposed within the susceptor sleeve, the inner liner further configured to convey the molten material from the submerged melting apparatus and comprising a liner end in proximity to, or in contact with, the sleeve end;
a top cap positioned over the sleeve end and the liner end, the top cap having the first refractory composition and configured to contact the molten material in the submerged melting apparatus, and the top cap further comprising an orifice substantially coincident with the liner end; and
an induction heating controller coupled to the coil and configured to inductively heat the susceptor sleeve to control a flow of the molten material through the orifice and the inner liner.
