A method is disclosed for preheating a molten salt electrolysis cell having an electrode which includes at least one element protruding into the interior of the cell. The method disclosed includes the distribution of a carbonaceous aggregate around such an element, and the ignition of this aggregate, so that the element may be brought to an elevated temperature without breaking due to the effects of thermal gradients.
