What this episode covers
Archaeological artifacts, like all things, degrade over time. Metals corrode, ceramics break into pieces, pigments change color, and the previous use of pesticide poisons create ongoing toxicity problems. How can they be best preserved for future generations? Scientists in the Arizona State Museum on the U of A campus are addressing this challenge at the intersection of archaeology, chemistry, and materials science. In this Episode: Nancy Odegaard Ph.D., Arizona State Museum, Professor of Anthropology, Conservator (ASM), Professor (MSE), University of Arizona; Leslie Tolbert, Ph.D, Regents' Professor in the University of Arizona's Department of Neuroscience
