Jonathan Cooke is an ICON Accredited Conservator-Restorer (ACR)
Jonathan served a traditional apprenticeship at York Minster, and established his stained glass conservation company, Jonathan and Ruth Cooke, in 1987. He has researched, explored and experimented with traditional painting techniques which now inform his restoration glass painting and original work alike. He has also worked alongside artists to realise stained glass windows to their designs.
He has been demonstrating and sharing his acclaimed multiple layering techniques with essential oils and other media throughout his career. His acknowledged generosity as a teacher has enabled many professional and amateur glass artists to adopt and explore these techniques, which are now widely and commercially exploited by others. His teaching on successful multiple layering was distilled into Time and Temperature, a manual on glass painting which was published by Swansea Metropolitan University in 2013. He is currently working on a companion manual on stains and enamels, and is one of three UK glaziers on a working party developing lead glazing and stained glass standards for Trailblazers, a government apprenticeship initiative.
His expertise and experience is called upon for the most challenging of projects: replicas include the decayed medieval stained glass of the Savile Chapel at Thornhill Parish Church, a copy of a Kempe window destroyed by arson, and the recreation of the lost Charity window for the Tivoli recess in the Soane Museum. The preparatory full size cartoon he produced and donated to the Museum, seen at right, was described by the Director as 'a work of art in its own right.' In 2018 he undertook the restoration of the Cliffe Castle grand staircase window for Bradford Council in a unique project featuring restoration, conservation and design elements.
2019 projects included the conservation of stained glass panels from the Frederick Leach stained glass workshops for the David Parr House, Cambridge
