Silver Saver

The video discusses the challenges of polishing silver items, which can wear away precious metal. At the Walters Art Museum, lacquer is used as a protective barrier, but it can alter the color of the items. Material scientist Ray Fanniff and his team are developing a new, nearly invisible protective coating using atomic layer deposition. This method allows precise control over the coating's thickness. The new coating is undergoing rigorous testing to ensure it outperforms current lacquers in protecting silver from tarnish. If successful, this innovation could preserve valuable items for future generations.
