Mirrors with Memory: Conserving Daguerreotypes from the Library and Archives Canada Collection – Part II

Glass Deterioration

Depending on conditions, the rates of deterioration of the materials that make up a daguerreotype package (e.g., copper, silver, paper, brass, leather, velvet, silk and glass) can vary substantially. One of the most common problems found by conservators is glass deterioration.

Glass deterioration often makes the daguerreotype appear dull and hazy. This does not necessarily mean that the plate itself has deteriorated. A number of the daguerreotypes from the Library and Archives Canada (LAC) collection that were prepared and treated for exhibition showed distinct signs of glass deterioration

Glass deterioration can occur as a result of fluctuations in either temperature or humidity. There are a couple of ways in which this type of degradation can manifest itself. One is cracking, which is when tiny hairline cracks appear on the surface of the glass. The other is chemical decomposition, which affects older glass with a higher concentration of sodium oxide, causing the glass to appear hazy or cloudy.

Keeping the original glass of a daguerreotype is always encouraged, and in cases where the glass is in an early stage of deterioration, e.g., it appears hazy or foggy, it can possibly be cleaned and reused. Treating this type of deterioration is relatively straightforward: the glass is removed, cleaned with distilled water and a neutral soap, rinsed with ethanol, then left to air dry. When placed back onto the daguerreotype, the plate will immediately appear brighter and clearer. Continue reading

John Boyd

As Canadians we appreciate discovering stories about our country through the works of our painters and photographers, past and present. Canadian archives hold many collections, and sometimes the collection of a particular artist or photographer may contain literally thousands of images for us to explore. This is the case with photographer John Boyd whose collection at Library and Archives Canada (LAC) boasts 28,959 black-and-white photographs.

John Boyd (1865–1941) was born in Emyvale, Ireland. His family immigrated to Toronto in the late 1860s. He was a railway official as well as a photographer. His work with the railroad gave him ample opportunities to take photographs as he travelled across Ontario.

These photographs represent Boyd’s amateur work from 1898 to 1926. A large collection in itself, it is nonetheless dwarfed by the collections held at the City of Toronto Archives. One collection in particular is that of The Globe and Mail, which contains 140,000 of Boyd’s photographic negatives taken from 1922 to before his death in 1941.

The collections at LAC and the City of Toronto Archives complement each other in their dates of creation and subject matter.

The John Boyd fonds consists of photographs portraying all manner of Canadian life, all worth exploring. There are images of towns and cities, royal visits, military life, modes of transportation, industry and agriculture, social conditions, pastimes, and nature.

During the First World War, Boyd focused mainly on the home front, photographing recruiting campaigns, training exercises, and the manufacture of munitions, airplanes and ships. He also photographed everyday Canadians who contributed to the war effort at home as soldiers fought overseas. The following selection of images provides a glimpse of the activities during that time.
