The relationship between liquid, supercooled and glassy water

Abstract

That water can exist in two distinct 'glassy' forms - low- and high- density amorphous ice - may provide the key to understanding some of the puzzling characteristics of cold and supercooled water, of which the glassy solids are more-viscous counterparts. Recent experimental and theoretical studies of both liquid and glassy water are now starting to offer the prospect of a coherent picture of the unusual properties of this ubiquitous substance.
