This book focuses on the experimental determination of the physical properties of silicate melts and magmas close to glass transition. Abundant new data are presented. The same type of measurement is performed on a range of melts to test the effect of composition on physical properties; and a range of different techniques are used to determine the same physical properties to illustrate the relationships between the relaxation of the melt structure and the relaxation of its physical properties. This book is of interest to experimental researchers in the discussion of data obtained from both a materials science and a geoscientific point of view.
Sharon Webb began writing with a poem published in The Magazine of Fantasy & Science Fiction in 1963. She initially used the masculine pseudonym "Ron Webb" and appeared only on occasion. In 1979 she became more productive and largely worked under her own name. Her works often concern medical issues or advances in medicine. Along with science fiction she has also written medically oriented thrillers. Sharon Webb began her writing career at the age of eleven when she won her first author’s award for an original work of poetry.
