Meditation and the Medieval Mind, an ongoing exhibition located on Level 1 of the Gallery, contains select works from the Thomson Collection of European Art, including a mid-16th century prayer book and a 17th-century miniature book finely gilded with silver. “In more historical paintings and works, like those from the 14th century and onwards, silver was at times used as a more affordable alternative to gold,” says Meaghan Monaghan, AGO Conservator, Paintings. “For frames and fine detail work, artists would gild silver leaf, and then tone it with a yellow paint so it would look like gold.” Also on Level 1 of the Gallery, Diptych: The Annunciation and the Man of Sorrows (ca. 1410) by Gonçal Peris Sarria is on view. In the right panel, the angels placed in the background look to be gilded with silver that has tarnished and darkened over time. Could this be an example of this resource-saving silver leaf technique? Possibly, but without an in-depth chemical analysis, it’s impossible to know exactly which metal has been used.
Fast forward to the 20th century. Andy Warhol, who famously donned wigs topped with grey-silver hair, revisited silver more than once in his work. And with his major exhibition on view until late October, we can see his well-documented use of the metal. “Silver was the future, it was space-y,” he recounted, “The astronauts wore silver suits. [Alan] Shepherd, [Gus] Grissom and [John] Glenn had already been up in them, and their equipment was silver. too. And silver was also the past–the Silver Screen–Hollywood actresses photographed in silver sets." Acquired by the AGO in 1979 and on view in the exhibition, Silver Liz as Cleopatra (1963) (image above) is one in a series of portraits Warhol made of Elizabeth Taylor in the early 1960s and one of many celebrity portraits he made. Taylor, a cinematic icon from Hollywood’s silver screen and perpetual tabloid fodder, appears silkscreened 15 times on the left side of a hand-painted silver canvas. The image is lifted from Taylor’s turn as the titular character in the 1963 film Cleopatra, a notoriously fraught production that was once the most expensive films ever made and went on to become the highest-grossing film of 1963. Taylor was paid more than $1 million for her portrayal–a landmark earning–making her the first actor to ever receive that amount. It’s no secret that Warhol had a fascination with celebrities. Much like contemporaries Marilyn Monroe and Judy Garland, Taylor represents the glamour and tragedy of 20th century Hollywood. Through this painting, Warhol comments on the fantasy and illusion of the silver screen. The strips of repeated silkscreen images are placed on the silver-painted background as if to hover over it. Silver Liz as Cleopatra (1963) and Elvis I and II (1964) are two of a small number of paintings in the AGO Collection that contain silver-coloured paint.
Around the same period, Warhol extended his fondness of silver to The Factory in midtown Manhattan. He tasked his collaborator and former partner Billy Name to cover the experimental art studio and gathering space in silver paint and reflective aluminum foil. It was in this large loft where mass production of Warhol’s paintings, sculptures and films took place. It quickly became a popular haunt for New York glitterati, attracting artists, friends and celebrities looking to partake in artmaking, and sometimes drug use. In 1966, Warhol unveiled Silver Clouds (1965-66) for the first time at Leo Castelli Gallery in New York. These helium-filled floating “pillows”, as they were once referred to, are made out of a silver laminate called Scotchpak. Echoes of Silver Clouds can be seen in Yayoi Kusama’s INFINITY MIRRORED ROOM - LET’S SURVIVE FOREVER, also part of the AGO Collection.
Warhol is known for his photography. His gelatin silver prints, such as his series of stitched photographs, make up a dedicated portion of the exhibition. But, what is a gelatin silver print exactly, and how is silver involved? The AGO has thousands of them in its Collection. A fibre-based gelatin silver print has four layers: a paper base, a baryta layer, a gelatin silver halide binder and a protective gelatin overcoat. In basic terms, silver comes in the form of silver halide particles suspended in the gelatin binder, which holds the photographic image. Highly sensitive to light, silver halides are chemical compounds formed with silver and halogens like bromide and chloride. To the naked eye, these prints don’t often look to have any form of silver in them. A well-printed, well-conserved gelatin silver print can appear warmer in tone (in part because of the gelatin binder and overcoat) with varying shades of grey, black and brown. The details of a print increases with the amount of silver halide in the photographic paper; the more silver, the more detailed the print can appear.
The first consideration for any gelatin silver print entering the Collection, or preparing to be exhibited, is its condition. “What I need to look at is if there is a breakdown of those layers,” Katharine Whitman, AGO Conservator, Photography, explained. “The layers need to be stabilized if the photograph is going to be exhibited safely.” Without proper protection from pollutants and fluctuations in humidity, a gelatin silver print can deteriorate as it ages. It may begin to look faded and discoloured with a yellow tone. Denser areas of the print can even take on a white-ish mirrored cast known as “silver mirroring”. This occurs when the filamentary silver halide particles begin to break down (like steel wool breaking apart) and accumulate into a cloud of broken smaller particles that can eventually migrate to the front-facing part of the image. West Indies Regiment Soldiers—a 1930 gelatin silver print from the Montgomery Collection of Caribbean Photographs—has some evidence of very minor “silver mirroring” along its left and right edges (see detail image). This doesn’t take into account physical wear and tear that can occur over time in the form of cracking and, in some cases, even mould. Some of the fibre-based gelatin silver prints from the Andy Warhol exhibition for example, had minor abrasions along their edges.
The daguerreotype process predates the popularization of the gelatin silver process by a few decades. Invented by Louis-Jacques-Mandé Daguerre, it's the first form of photography, and includes silver as well—an image created on a sheet of polished, silver-plated copper. The introduction of the gelatin silver process in the late 1880s, however, changed photography fundamentally. “It became popular in the 1880s because it was replacing photographic processes that were even more complex, labour intensive, and could only be professionally done,” explains Whitman. “The introduction of gelatin silver photography made it possible for anybody to take photographs.” Anyone with access to a camera, like a Kodak “Brownie” box camera, could take their own photographs, and have them developed and printed for them. The gelatin silver process remained a popular choice for professionals and hobbyists alike well into the 20th century. Nearly all photographs up until roughly the 1970s were fibre-based gelatin silver prints. The widespread popularity of colour photography in the 1960s and digital photography in the 1990s ultimately led to the gelatin silver process becoming less common. A variety of gelatin silver prints from the AGO Collection are on view on Level 1 in Documents, 1960s-1970s. Fragments of Epic Memory will feature a selection of just over 200 images from the Montgomery Collection of Caribbean Photographs beginning this September, including several examples of gelatin silver prints and daguerreotypes taken in the post-emancipation period in the Caribbean.
