Common sand and glass are both made primarily of silicon and oxygen, yet sand is opaque and glass is transparent. Glass owes its transparency partly to the fact that it is not a typical solid. On the molecular level, solids usually have a highly regular, three-dimensional crystalline structure; the regularities distributed throughout the solid act as mirrors that scatter incoming light. Glass, however, consists of molecules which, though relatively motionless like a typical solid, are not arranged in regular patterns and thus exhibit little scattering; light passes directly through. At a specific temperature, called the melting point, the intermolecular forces holding together the components of a typical solid can no longer maintain the regular structure, which then breaks down, and the material undergoes a phase transition from solid to liquid. The phase transition in glass, however, depends on how quickly the glass is heated (or how quickly it cools), due to its irregular solid structure.
First recorded before 900; Middle English noun glas, Old English glæs; cognate with Dutch, German Glas
Glass is the hard, transparent material that's used to make windows. While glass can be strong and sturdy, it's also brittle and can be broken easily by an errant baseball. Glass has all kinds of practical uses, from car windshields to greenhouse windows to jam jars to drinking glasses. When someone offers you a glass of water, they're referring to the vessel itself as a glass and also to amount it can hold — the glassful of liquid. The Old English source of glass is glæs, ultimately from a Proto-Indo-European root that means "to shine."
