Abstract

A method of forming a glass melt including heating a glass feed material in a first melting furnace to form a glass melt, flowing the glass melt into a second melting furnace through a refractory metal connecting tube, and further heating the glass melt in the second melting furnace. The refractory metal connecting tube is heated to prevent the molten glass from excessive cooling, and to ensure that the glass melt entering the second melting furnace is equal to or greater than the temperature of the glass melt in the second melting furnace. An apparatus for performing the method is also disclosed.
