Although completely self-contained, this book forms a useful supplement to Volf's "Chemical Approach to Glass" (1984) in which the account of the manifestation of the individual elements in oxide glasses was described phenomenologically. Aimed at facilitating active study of glass by means of calculations, this book is directed towards a quantification of the manifestation of elements in glass and interpolation of the chemical and physical dependence of the properties of glass. Thanks to the availability of computer technology and to increasing cooperation between glass scientists and mathematicians, the field of applied mathematics in glass has expanded and is developing into a separate discipline with its own systems and methods, internal classification, and links to other disciplines. The concept of calculations in glassmaking has therefore outgrown its original scope. It has ceased to be a mere collection of formulas and tables and is moving away from the apparently accidental peculiarities related to the nonstoichiometry of glass to an order dictated by the periodical system of elements.
