In the process for producing molded bodies from precursors of oxidic high-temperature superconductors a copper mold of the desired shape which encloses a solidified bismuth strontium calcium cuprate melt is treated with a solution of a soluble compound containing sulfate anions, an aqueous mineral acid and an oxidizing agent until the copper mold is dissolved. A protective layer of at least one of strontium sulfate or calcium sulfate is formed on the solidified melt.
