Superconducting Bi-2212/Ag wires and tapes have been fabricated by the ``powder in tube`` method. Using three-stage annealing, the scatter in j{sub c} data has been reduced to typically 10 % for the wires. Average critical current densities up to 79,000 A/cm{sup 2} (B = 0) and 28,000 A/cm{sup 2} (B = 12 T) have been reached at 4.2 K. For textured Bi-2212/Ag tapes j{sub c} values of about 40,000 A/cm{sup 2} at 4.2 K and B = 12 T have been achieved. X-ray diffraction indicates imperfect grain alignment.
