The Viscoscity of Synthetic and Natural Silicate Melts and Glasses at High Temperatures and 1 Bar (105 Pascals) Pressure and at Higher Pressures, U.S. Geol. Surv. Bull. 1764



Over the past decade, I have routinely collected papers dealing with the physical properties of rocks and other materials. Their dog-eared and coffee-stained appearance is just one indication of their continuing value to me. Focusing on viscosity of silicate melts, Michael Ryan and James Blevins have considerably extended and formalized this collection process, resulting in the publication of a massive report containing viscosity data on an extensive variety of melt compositions. According to the authors, this report represents an initial step in establishing a comprehensive U.S. Geological Survey (USGS) data base for the properties of multicomponent silicate melts.
