Presents the results of direct calorimetric determinations of the heat of mixing of NaAlSi3O8 and H2O to form hydrous melts and glasses. Our results help to explain geological phenomena such as the high water contents of perlitic obsidians and the lack of thermal magma quenching accompanying exsolution of dissolved water in explosive volcanic eruptions. -from Authors
