A Cascade of droplets in a mixture of molten glass

Researchers from CNRS, ESPCI Paris, and Saint-Gobain used a 3D imaging technique of X-ray micro-tomography to follow the evolution of a mixture of molten glass at high temperature. They shed new light on an original mechanism of liquids fragmentation, which might apply to texturing glasses at tiny scales. Their work was recently published in Physical Review Letters.
