Abstract

A waveguide assembly (10) is provided for imparting ultrasonic energy to a glass melt (12) at an amplitude sufficient to produce acoustic streaming in the melt, thereby mixing the molten glass. The glass melt (12) may, for example, be flowing through a refractory metal vessel (14). In one configuration the waveguide assembly (10) includes a waveguide (18) acoustically coupled to a transducer (16) at one end (22) and the glass melt (12) at the other end (20). The waveguide (18) may be physically coupled to the vessel (14) via a threaded fitting (32, 34) attached to an outside surface of the vessel (14).
