Fractures are discussed theoretically and practically. This book represents a conscious effort on the part of the author to detail the "life" of a crack, from its inception, through its growth, to its culmination. The author is careful to define all key terms within the text, making this book an excellent reference for anyone working with brittle materials.

Quality Assurance in Ceramic Industries represents the proceedings of a conference held at the New York State College of Ceramics, Alfred University, June 4-7, 1978, as fifteenth in a continuing series rotated annually among Alfred University, North Carolina State University, Notre Dame University and the University of California, Berkeley. The first four chapters develop the rationale for major efforts toward an integrated quality assurance program in the ceramic plant, to effect economy in manufacture, to reduce process losses and to improve product reliability and overall profitability. Chapters 5 and 6 cover the use of traditional and advanced statistical methods. They are followed by three chapters on quality assurance in raw materials production and procurement. Chapters 9 through 20 treat specific examples of techniques, sys­ tems and philosophy of quality assurance in glass, whitewares, abrasives, refractories, electroceramics, structural clay pro­ ducts and special ceramics for nuclear applications, turbines and igniters. The three concluding chapters deal with the broadly applicable subjects of failure analysis, gaging and life­ time predic tion. It is a pleasure to acknowledge the generous help and encouragement of the Program Committee: Messrs. R. A. Alliegro, Norton Company; D. L. Guile and R. N. McNally, Corning Glass Works; H. W. Larisch, Coors Porcelain Company; R. H. Lester, Ohio Brass Company (now at the Lapp Insulator Division of Interpace Corporation); R. J. Ryder, Brockway Glass Company and E. A.

Boron Oxide plays a key role in numerous glasses of high technological importance, yet its role in glass structure is far from clear. Indeed, in recent years there have been serious chal­ lenges to previous structure concepts for both crystalline and glassy borates. These challenges were sufficient to warrant a re­ examination of the structure of borate glasses using the most pow­ erful tools currently available. To provide a suitable forum for this undertaking, a four-day conference on "Boron in Glass and Glass Ceramics" was convened at Alfred University, June 3-8, 1977 to review the best scientific thinking on structure and to debate conflicting views and discuss properties and applications of borate glasses. This conference was also the first in a New University series on Glass Science to be rotated among Alfred University, The Pensyl vania State University, Rensselaer Polytechnic Institute, and the University of Missouri-Rolla. The present volume represents the proceedings of the first conference in this series. The volume begins with a review of the remarkable contribution of Jan Krogh-Moe to the understanding of the structure of Borate glasses. This review, authored by Professor N. J. Kreidl, concludes by dedicating the proceedings of this conference as a Krogh-Moe Fest­ schrift. The volume continues with a historical review by D. L. Griscom, originally prepared for circulation to the contributors prior to the conference. An Epilogue to the opening chapter brings the survey up-to-date in light of the conference papers.
