The deposit of copper obtained at the cathode in the electrolysis of the fused chlorides, was always crystalline, feathery, and loosely adherent. The nature of the deposit was not affected by varying current densities. To obtain quantitative result...s, two difficulties must be overcome. 1st. The temperature must be maintained uniform throughout the cell, to prevent the formation of thermo-electric couples* These couples, occuring on the same electrode or between parts of the two electrodes, could not affect the quantitative results, provided the copper be precipitated in a dense, adherent form* Such is not the case. If the electrolysis is carried out in a crucible heated by a Bunsen burner, nodules of non-adhering copper appear on the electrodes* Local high current densi- ties, must occur and prevent an adherant deposition of copper.
