Over the past 20 years, chemist Marvin Rowe of Texas A&M University has developed a nondestructive method for carbon dioxide extraction.In his process, an object is placed in a vacuum chamber and a supercritical fluid—a hybrid gas/liquid—is applied as a solvent (as in dry cleaning).Next, Rowe passes plasma—an "electrically excited ionized gas"—over the artifact, which selectively strips carbon from the sample."It's essentially like slowly burning the sample, so we can just oxidize a little off the surface and collect that carbon dioxide," explains Rowe.This year he further refined the method so it will work on objects coated in sticky hydrocarbons, such as the resins that cover Egyptian mummy gauze.Thus far, he's dated samples of wood, charcoal, animal skin, bone from a mummy, and ostrich eggshell.
