Breaking local symmetry: Why water freezes but silica forms a glass

Research at The University of Tokyo's Institute of Industrial Science reveals that water and silica diverge when cooled due to differences in atomic arrangement. Water's strong orientational order leads to easy crystallization, whereas silica's weak ordering results in supercooling and glass formation.
