Scientists have for the first time visualized the transformation of powder mixtures into molten glass. A better understanding of this process will make it possible to produce high quality glass at lower temperatures, leading to significant energy savings in industrial glass manufacturing. The results are published in the Journal of the American Ceramic Society. The team of scientists was led by Emmanuelle Gouillart from the joint research unit between CNRS and Saint Gobain, a global glass manufacturer, and included scientists from the Universities of Toulouse and Grenoble, INRIA Saclay and the European Synchrotron Radiation Facility (ESRF) in Grenoble. The scientists set out to understand what exactly happens at the different stages of the transformation from powder to molten glass.
