This book presents state-of-the-art information concerning properties and processes involved in glass melts. Based upon contributions by renowned authors and scientists working with glass melt systems, Properties of Glass-Forming Melts is an excellent compilation of the current knowledge on property data, mechanisms, measurement techniques, and structure-related properties of glass-forming. The authors provide in-depth analyses of such topics as glass-melt density, thermal expansion, heat conductivity, and chemical activities. Each chapter combines fundamental concepts with a compilation of recent and reliable data that is essential in the modeling of glass melting, fining, conditioning, and forming. The book first discusses the glass-forming melts, thermodynamics, transport properties, and redox effects of glass. This provides a sound basis to the analysis of important properties of glass melts such as viscosity, surface tension, density, and heat capacity as well as more generalized subjects of heat transfer and gas solubility. A chapter on electrical properties provides a solid foundation for understanding glass melting via direct Joule heating of the melt. The examination of the corrosive nature of molten glasses will be of great interest to tank designers and operators. This unique handbook concludes with an overview of nuclear waste vitrification, a growing discipline that relies on current data and encourages research in glass melts. This book is an ideal starting place for future-generation glass scientists and an effective reference for scientists who require data on the behavior of viscous melts and for glass technologists who apply mathematical models simulating the meltingand forming processes. Properties of Glass-Forming Melts offers a one-of-a-kind and valuable source of reliable data and insight by those with firsthand knowledge and experiences in this field.

This is a digital reprint of David Pye's original 1968 edition. Within it he argues that the aesthetic quality of our environment depends as much on its workmanship as on its design, and that workmanship has been largely ignored. He proceeds to develop a new theory of the aesthetics of workmanship which can be applied to architecture, to the products of industry and to craft work. Mr Pye shows how and why we are conscious of finish and workmanship, goes on to ask why so much of our environment is impoverished and asks what can be done about it.

This is David Pye's classic book on the theory of design. In it, he explores the many facets of good design, including the relationship of aesthetics with function.

This is one of the classic books on craftsmanship and design. In it, David Pye explores the meaning of skill and its relationship to design and manufacture. Cutting through a century of fuzzy thinking, he proposes a new theory of making based on the concept of good workmanship and shows how it imparts all-important diversity to our visual environment.
