Crystallization Kinetics of SiO2 at High Pressures
The unusual enhancement of certain kinetic phenomena at high pressure in some Silicates has long been a source of interest. Shaw  noted a decrease in the viscosity of obsidian glass with pressure, though he attributed it to experimental uncertainties. Kushiro et al. [2,3] found that such a decrease clearly occurs in several Silicate melts. Uhlmann, Hays, and Turnbull  observed a large increase in the rate of crystallization of silica glass at high pressure. They showed that the increase scaled with the amount of water present and this might even account for the entire effect.
