More than 20 years ago, the Society of Glass Technology published a series of papers outlining the many advances in refractory technology that had contributed significantly to furnace performance and glass melting. In the intervening years, on-going developments, particularly in refractory technology and furnace design, have again contributed to further progress in energy efficiency, output and life of a glass melting furnace, and in the quality of their products. In recognition of this, those earlier papers have been extensively revised and are offered in this publication. The papers are intended for the non-specialist. They have been written to give a practical introduction to the properties, application and performance of the most important types of refractory, currently used in glass furnace construction.
