Abstract

A system is provided for characterizing a molten glass, wherein a waveguide (20a) is acoustically coupled to an exterior surface (34) of a vessel (10) retaining a quantity of glass melt. An acoustic wave is imparted into the glass melt (15) by a first transducer (24a) through a first waveguide (20a) wherein portions of the wave are reflected within the glass melt and received through a second waveguide (20b) and a resulting signal is produced by a second transducer (24b) and analyzed to characterize the glass melt.
