materials analysis to archaeology. She worked for example, on the dating of prehistoric bronze, copper and ceramic artifacts. One small example of her work in this field regards what was a standing question on the nature of shiny black Chinese mirrors found in high quantities in ancient tombs. Franklin's use of microscopic, etching, electron microprobe and x-ray fluorescence analyses produced evidence that what was thought by some to be a corrosive effect was in fact present in these ancient mirrors (and weapons) at their inception, in dark iron oxides intentionally added near the objects' surfaces. Franklin additionally pulled from historic and literary accounts of black mirrors in Chinese literature to support these findings. Franklin's expertise was also instrumental to dating glass; she guided a study on the remains of blue glass beads in North America remaining from early trade relationships between American Indian tribes and Europe. In the early 1960s Franklin was one of a number of scientists who participated in the Baby Tooth Survey, a project founded by Eric and Louise Reiss along with other scientists such as Barry Commoner, which investigated levels of strontium-90—a radioactive isotope in fallout from nuclear weapons testing—in children's teeth. This research contributed to the cessation of atmospheric weapons testing. Franklin published more than a hundred scientific papers and contributions to books on the structure and properties of metals and alloys as well as on the history and social effects of technology. As a member of the Science Council of Canada during the 1970s, Franklin chaired an influential study on conserving resources and protecting nature. The study's 1977 report, Canada as a Conserver Society, recommended a wide range of steps aimed at reducing wasteful consumption and the environmental degradation that goes with it. The work on that study helped shape Franklin's ideas about the complexities of modern technological society. Activism Franklin was also active in the Voice of Women (VOW), now the Canadian Voice of Women for Peace, one of Canada's leading social advocacy organizations. In 1968, she and VOW national president Muriel Duckworth presented a brief to a House of Commons committee asserting that Canada and the United States had entered into military trade agreements without adequate public debate. They argued that these commercial arrangements made it difficult for Canada to adopt independent foreign policy positions such as calling for an immediate U.S. military withdrawal from South Vietnam. In 1969, Franklin and Duckworth
