We are privileged this year to have four excellent Keynote Speakers whose combined expertise spans the full spectrum of glass-related fields of study.   Their initial specialisms range from nuclear chemistry to archaeology, and from hands-on architectural conservation to system engineering and engineering management.   Brought to a focus in the multifaceted arena of glass heritage these skills turn a confusion of mundanity into a splendour of insight.


Stephen P Koob

Stephen P Koob received an MA (1976) in Classical Archaeology from Indiana University, and a BSc (1980) in Archaeological Conservation and Materials Science from the Institute of Archaeology, University of London. He spent five and a half years as conservator of the Agora Excavations with the American School of Classical Studies in Athens, Greece. From 1986-1998 he worked as conservator, specializing in ceramics and glass, at the Freer Gallery of Art and Arthur M. Sackler Gallery, Smithsonian Institution, Washington, D.C.
In 1998 he came to The Corning Museum of Glass, where he is now Chief Conservator. He also continues teaching archaeological conservation at the site of Samothrace, in northern Greece, and has numerous conservation interns at Corning. He has recently published a book, “Conservation and Care of Glass Objects”.




Jonathan Cooke

Jonathan Cooke ACR trained at the York Glaziers Trust where he learnt the traditional techniques and methods for the creation,conservation and restoration of stained glass, working on the restoration of York Minster following the fire of 1984. He has been a freelance conservator and glass painter since 1987, during which time has had the privilege of working on glass of all dates and the challenge of replicating damaged painted surfaces, sometimes on a large scale, including for all major c19 English workshops,.Jonathan has been a regular contributor at conferences in the UK, Europe and the USA. He presented a paper in September 2017 on the techniques of late c19 English stained glass workshops at the International CVMA conference in Cambridge, which was also published in a peer- reviewed volume, Art at the Surface: Creation, Recognition, Conservation. Having established a reputation as one of the leading exponents of restoration glass painting of all periods, Jonathan has given classes in glass painting throughout the UK, as well as in Norway and the USA. He is a mentor for ICON, and for the Livery Companies’ pilot apprenticeship scheme. Internationally, he has undertaken workshops for the American Glass Guild in New Jersey, and Orlando, Florida, and in Norway for Trondheim Cathedral.
His manual on glass painting ‘Time and Temperature’ published by Swansea Metropolitan University in 2013, is a practical guide to a variety of techniques; a distillation of his working knowledge and experience, observation and study.

Colin Brain

Colin is an engineer by training. He served a six-year apprenticeship, has a Master of Science degree, a Diploma in Engineering Management and is a Chartered Engineer.
In 2002 he was elected a QinetiQ Fellow for his work on system engineering verification (have we built the thing right?) and validation (have we built the right thing?).
In 2004 he founded his own specialist company which worked internationally for 10 years.
With first wife Sue his interest in the history of glass dates back fifty years. Currently president of the Association for the History of Glass he has written and lectured on a variety of glass-history topics, particularly the development of British Crystal glass in the sixty years 1642-1702. Colin & Sue had three papers on this field published Glass Technology. Sadly Sue died of cancer in 2006 and did not live to see the last one in print. Colin’s second wife Sylvia who was helping write a fourth paper has sadly also recently died of motor neurone disease.


António Pires de Matos

António secured a Degree in Chemical Engineering from the Technical University of Lisbon in 1962, and in 1970 was awarded PhD in chemistry by the University of Cambridge, U.K.
After 40 years of research in radiochemistry at the Portuguese Nuclear Institute, where he was Coordinator Researcher, António was invited to teach Methods of Instrumental Analysis in the course of Conservation and Restoration at the Universidade NOVA de Lisboa. In 2002, with colleagues of the Faculty of Fine Arts of the Universidade de Lisboa, he founded the research unit “Glass and Ceramics for the Arts”, VICARTE. António is Emeritus Invited Full Professor at the Universidade NOVA de Lisboa and now is working at the Research Unit VICARTE in the campus of this university.
His current research activities are divided in provenance studies of Portuguese glass and new techniques to colour glass – applied to contemporary art. He has been studying several historic batch books, namely from Portugal, from the Rakow Library of the Corning Museum of Glass, from Venice and from the Dudley Archives in England.
