Nicholas Dorman, chief conservator for the Seattle Art Museum, motions toward an old x-ray of the art as he talks about his on-going restoration work of Jackson Pollock’s painting Sea Change during a news conference Tuesday, Nov. 27, 2012, at the museum in Seattle. The celebrated piece, part of SAM’s permanent collection, was painted in 1947 and altered in 1970 with a coat of varnish. Dorman is several months into the restoration work, which is complicated by the uneven surface and multiple layers of media, including several types of paint and imbedded gravel. The restoration is sponsored by Bank of America’s Art Conservation Project, which enabled SAM staff and consulting experts to undertake a study of the original materials and evaluate the impact of materials used in conservation treatments.

SEATTLE [auth] (AP) — The Seattle Art Museum is restoring a 1947 Jackson Pollock painting that was altered in the 1970s with a coat of varnish.
Work started last summer in the museum’s conservation studio on “Sea Change.” It’s a cornerstone work in the museum’s permanent collection that represents Pollock’s transition to a drip technique.
Reporters and photographers were invited Tuesday to see how recovering the original surface of “Sea Change” reveals the method and intent of the artist who died in 1956.
The restoration is especially complicated because of the multiple types of media and the depth of the surface, said Nicholas Dorman, chief conservator for the museum.
The painting is about 4-by-5 feet in size and includes many layers, beginning with a fine weave canvass, then a white oil base, brushed color images, aluminum paint drips, black drips with imbedded gravel (some pieces of which have come off during transit over the years) and then dabs of pure color.
Several types of paint are used, including oil, house and other commercial paints and possibly an early acrylic paint.
It’s taking months of work as Dorman carefully uses solvents to remove four-decade old varnish. The restoration also requires a certain level of detective work and research to establish as much information as possible about the original piece. That includes whether it was painted on an easel or on the floor, looking at old X-rays for further details and at old photos of Pollock at work to try to glean any possible additional information that could be helpful.
Because of how the varnish works with the original materials over time, it was important to do this work now, Dorman said. It would just be too late if there were any further delay.
The restoration is additionally complicated because some of the materials by their nature are shiny and others are matte. So, as Dorman works removing the shiny varnish, the changes are subtle. And because of the multiple materials, the restoration process itself becomes a research project to find what solvents work best for such restoration — information that is expected to be valuable to others working in the field.
The work is funded by the Bank of America’s Art Conservation Project, which has provided about $2 million since 2010 to restore art and artifacts of cultural and historical value in countries around the world.
