Abstract
Glass melts have been imaged by x-ray computed tomography at temperature to gain understanding of the morphology and thermal gradients in a melter. Two scales of melting have been carried out. First, pressed pellets of dried glass-forming chemicals have been heated to homogenous melts with the foam structure analyzed. Second, a 10-cm scaled analogy of the Hanford Waste Treatment and Isolation Plant has been engineered for operation in a x-ray computed tomography scanner to make measurements of foam structure and heat gradients below the cold cap. The rate of melting and heat flow from the melt into the reacting glass-formers have been inferred from morphological and thermal measurements taken during melting. These are novel measurements which validate temperature models for the first time.
