Quartz dissolution during the batch-to-glass conversion influences the melt viscosity and ultimately the temperature at which the glass forms. Batches to make a high-alumina borosilicate glass (formulated for the vitrification of nuclear waste) were heated as 5°C min-1 and quenched from the temperatures of 400-1200°C at 100°C intervals. As a silica source, the batches contained quartz with particles ranging from 5 to 195 µm. The content of unreacted quartz in the samples was determined with x-ray diffraction. Most of fine quartz has dissolved during the early batch reactions (at temperatures
