This important and classic scientific study by Mr. Volf, has been one of the most impossible books to find. Very few libraries, public or private have this book until now. This is a very technical description on the chemistry, definition, and constructions of glasses. The properties of various glasses and their relationship to various elements and their effects on glass are covered. Numerous tables, formulas, figures and references are found throughout the book. Recommended for glass scientists, engineers, laboratories and reference libraries. Artists and craft people may be looking for information in much more depth will also want this book.

Firing Schedules for Glass takes much of the guesswork out of studio glasswork by making it easier to select the right schedule for the firing circumstance. The manual provides firing schedules for computers and digital kiln controllers. This vital information is also relevant for "manual" firings. - Has 100 pages of schedules, formulated for both Celsius and Farenheit.- Includes rates of heating glass up, not just down.- Largely removes the task of calculating a schedule for each glass thickness.- Provides, on the one schedule page, the figures for different glass types.- Offers schedules based on glass thickness, on time and on purpose.- Lists common firing variables.- Provides a means of accommodating variables without calculation.- Relates schedules to kiln type, and control type.- Includes schedules for glassblowing and lampworking. Contains a further100 pages of technical background information. - Incorporates an extensive glossary, bibliography and index.

Why does someone write a book about Tungsten? There are several reasons and precedents for this, the most important of which is that the last book on tungsten was written more than 20 years ago, in 1977, by St. W H. Yih and Ch T. Wang. During the intervening period there have been many new scientific and technological developments and innova tions, so it was not only our opinion but the view of many other members of the "tungsten family" that it was time to start writing a new book about tungsten. Preparations of the new book began in 1994. further impetus to the project was provided by the realization that in spite of this new knowledge having been presented at seminars or published in the technical press, a general acknowledgement of it by the majority of technicians and scientists is still far from being realized. It is our hope that this book will significantly contribute to a broader acceptance of recent scientific and technological innovations. An important prerequisite for such a project is the availability of a recently retired, experienced person willing to devote his time and talents to the tedious part of the exercise.

The report presents a detailed review of available information on the oxidation of W and its alloys. W is relatively inert below 700 C. As the temperature is increased above this level, however, oxidation becomes progressively more rapid, reaching catastrophic rates at temperatures around 1200 C and above. Various theories for the mechanism and rates of W oxidation at different temperatures are reviewed, and the effect of pressure and water vapor on the stability of W oxides is discussed in detail. The elevatedtemperature reactions of W with other materials, such as refractory oxides, and with gases other than oxygen also are covered. Information on the protection of W by alloying and coating is included. (Author).
