When I joined BCRA (as it was then known) to work for Dr A.E. Dodd, the second edition of this dictionary was well in hand. As a newly-qualified physicist, I contributed a few specialised entries. Nearly 30 years later, many more are required. The dictionary has been considerably expanded to take account of new developments in engineering ceramics, electroceramics; of new processes in whitewares; of new machinery and new test methods; of the impact of environmental legislation. The same broad scope has been adopted and coverage of glass, vitreous enamel and cement industries widened. It has seemed wise, in an industry which has moved much further to being science-based rather than craft-based, to include some terminology in relevant areas of basic science: in particular crystal structure, fracture mechanics and sintering. Here, and for some advanced ceramics produced in a wide variety of forms, some longer entries have been introduced to avoid extensive use of cross-references and to provide a coherent understanding of closely-related materials and processes.

Abbreviations have become something of a disease. Those in general use have been listed in their appropriate alphabetical positions, but where authors substitute (unrecognized and sometimes unrecognizable) initials for well-known processes as a shorthand, the obscurity resulting from carrying them over unexplained to another context cannot be clarified even by a multitude of dictionary entries. Such have been omitted.

About 2000 new terms have been added. Though some existing terms have been modified to take account of changed emphases (roller hearth kilns are not the rarities of 30 years ago), very few have been removed. This is a twofold tribute to Dodd's original work. His definitions, concentrating on the essence of the meaning, have stood the test of time, even when the words now have much broader application in details. Where words have become obsolete, it has been thought worthwhile to preserve his accurate and authoritative definitions for historical record. My thanks are due to The Institute of Materials for giving me the opportunity to revive Dodd's Dictionary; to Mrs Dodd for permission to use the original copyright material; to Dr R.C.P. Cubbon, then Deputy Chief Executive of British Ceramic Research Ltd, for allowing me to use the Company's library - without which this revision would have been impossible; to the staff of the Information Department there, past and present, who have all shared in gathering the information on which this book is based; and finally, to all my other ex-colleagues and friends in the industry, whose continued penchant for asking awkward questions has been the driving force and reason for that collection. D. Murfin Madeley, 1994
