Conservation of Photographs on Glass Symposium and Workshop

Wednesday, 10 October, 2018 to Friday, 12 October, 2018

Location: Art Gallery of Ontario (AGO), Toronto, Canada
Instructors: Katharine Whitman, Conservator of Photographs, Art Gallery of Ontario and Greg Hill, Senior Conservator of Archival Materials and Photographs, Canadian Conservation Institute.

Workshop Description:
The symposium will feature a day of lectures for photograph conservators and care-takers alike: the lectures will cover the history of photographs on glass and the history of glass, as it relates to photography. Speakers on this day will be Katharine Whitman, Stephen Koob, head of glass conservation at the Corning Museum of Glass in Corning, New York, and Sophie Hackett, curator of photographs at the AGO. There will also be an expert panel discussion including Lisa Ellis, Sophie Hackett, Stephen Koob and Katharine Whitman on glass and photographs in the AGO collection.

The two day workshop will provide training to conservators of photographs (10 max). The workshop will cover the deterioration and conservation of glass supported photographs, including reassembly of broken glass components and the current best practices for preservation and conservation. The workshop will be led by principal instructor, Katharine Whitman, one of the leading experts in the conservation of photographic materials containing glass. Greg Hill, senior conservator of archival materials and photographs at the Canadian Conservation Institute will be the co-instructor for this course. The hands-on practicum sessions, lectures, presentations, and discussions of the workshop will be comfortably accommodated in the AGO conservation studio and a lecture room. Selections from the collection of glass-based photographs and photographs with glass at the AGO will provide examples to illustrate the course curriculum.

The workshop will begin with comprehensive overviews of the use of glass in photography, its technology, mechanisms of deterioration, and diagnosis and documentation of condition. Processes to be covered will include both photographs with glass supports and photographs with associated integral glass components:

- Negatives (wet collodion, albumen, gelatin dry plate)
- Ambrotype
- Autochrome
- Lantern slide
- Opaltype
- Daguerreotype cover-glass
- Passepartout glass

This will be followed by presentations on best practice for treatment, storage, handling, and display. Hands-on practicum sessions with mock glass objects will provide experience with conservation treatments such as cleaning, consolidation, and various methods of stabilization of broken photographs.
