Electric art

The restoration of artworks is a tricky undertaking: There is often a danger of damaging the artwork when maintenance and repair are being performed on the objects. Using electrodes and a potentiostat from Metrohm and Metrohm Autolab, metal conservators from Amsterdam's Rijksmuseum and scientists from the Haute Ecole de Conservation-restauration Arc in Neuchâtel, Switzerland, have developed a new tool for the electrolytic cleaning of delicate silverware.
