This patent describes an apparatus for making a composite high-temperature superconducting wire, comprising a refractory core having a melting point above a melt temperature of a superconducting oxide ceramic having a critical temperature T{sub c} above 23{degrees} K and a layer of the superconducting oxide ceramic on the core. It comprises means forming a controlled-atmosphere chamber; a vessel received in the chamber and formed with an opening at a bottom thereof, the vessel receiving an annular mass of the superconducting oxide ceramic in solid form surrounding a passage traversing the mass and extending upwardly from the opening; means for forming a melt of the superconductive oxide ceramic in a small pool in the mass above the passage and at a temperature slightly above a melting point of the superconducting oxide ceramic; means for drawing the refractory core through the opening, the passage and the melt in succession and depositing the melt on the core, the pool being in contact only with the mass, the core and the atmosphere; means in the chamber above the pool for cooling the melt deposited on the core by radiation and convection.
