A method for rapidly melting glass-making materials wherein the glass-making materials are introduced into a chamber containing molten glass, heat is applied to the materials in the chamber by passage of an electric current between spaced electrodes while one of the electrodes is moved within the molten materials to agitate the materials to constantly move the location of the heating point through the batch glass-making materials and to enfold newly-added glass-making materials into the molten glass within the chamber.

A method of continuously mixing and melting glass-making materials which comprises: heating glass-making materials in a chamber to provide a pool of molten glass; positioning a plurality of electrodes within said chamber; positioning a rotatable bladed stirring device in said molten glass; applying electric current between said stirring device and said electrodes to provide a Joule heating effect in the molten glass between the stirring device and the electrodes in said chamber; rotating said stirriNg device in a circular path in a vertical plane, about a horizontal axis at a rate sufficient to produce a vortex in the glass at said vertical axis; introducing additional cold glass forming batch materials continuously into said chamber and into said vortex; continuing the application of electric current to mix and melt said added batch materials rapidly by the combined action of the already heated molten glass in the chamber and the stirring device; and continuously removing the molten glass from the chamber, said molten glass having gaseous inclusions therein.
