Caption: Melt-quenched silica. Molecular computer graphic of melt-quenched silica (silicon dioxide, SiO2). This image was produced by a sophisticated compu- ter program that models the molecular dynamics of compounds undergoing physical or chemical changes. The silica was melted (its true melting point is 1610 Celsius) and then suddenly solidified, or "quenched". The tortuous surface and holes in the crystal structure are shown here with a solid blue surface. The silica is in a semi-crystalline form with silicon atoms in yellow and oxygen in red.
