Working diligently to remove a gray salt layer from a million individual pieces of glass, three Czech conservators and a UCLA Engineering professor have been restoring a renowned mosaic in central Europe.

Materials science is forging its way into the future with new technologies in metallurgy, optics and nanotechnology – but one of its more surprising applications is its recent marriage with the world of medieval art.
UCLA Engineering professor Eric Bescher has been traveling to Prague for a decade now, applying a material he and his colleagues created to a mosaic titled “The Last Judgment.” The application of the substance, called sol-gel, is meant to prevent weather corrosion that could cause the pieces to be obscured forever.
