The Science of Protecting Antique Silver
The National Science Foundation's* latest Science Nation piece looks at a team of conservateurs working to protect antique silver from overpolishing, heavy lacquer and the ravages of time.
A material scientist and his team have developed a technique called "atomic layer deposition" to protect the precious material. The hope is that this nanometer-thick transparent coating will protect the silver from tarnish and wear.
"The films conform to the recesses and protrusions of the silver, creating a protective barrier," reports NewsHour science correspondent Miles O'Brien, who talked with the researchers as they tested the new material in the lab.
