Ancient Roman lead discovered 20 years ago in a shipwrecked vessel has been transferred from a museum on the Italian island of Sardinia to Italy’s National Institute of Nuclear Physics (INFN). The 120 lead ingots will be melted into a 3-centimeter-thick lining that will surround the CUORE (Cryogenic Underground Observatory for Rare Events) detector, which will investigate neutrinos when it begins operations next year. The Roman vessel is estimated to have sunk between 80 B.C. and 50 B.C.
