Disclosed are methods for making normal metal-clad superconductive bodies (20) (e.g., wires, ribbons) having a normal metal cladding (22) that is porous during at least a part of the manufacture of the body. The porous cladding permits access of an ambient atmosphere to the superconductive material. Exemplarily, the superconductive material is an oxide such as a (Ba, Y) cuprate, the normal metal cladding comprises Ag particles (or Ag-coated particles), and the body is heat treated in an oxygen-containing atmosphere. |
