THE METHOD OF ANODICALLY REDUCING THE THICKNESS OF A METAL WIRE WHILE MOVING THE WIRE THROUGH A LIQUID ELECTROLYTE, THE PROCEDURE COMPRISING MAINTAINING OVER THE UPPER LEVEL OF THE LIQUID ELECTROLYTE AND IN CONTACT THEREWITH OVER ITS ENTIRE UPPER LEVEL A LAYER OF AN ELECTRICALLY INSULATING LIQUID HAVING LOWER SPECIFIC WEIGHT THAN SAID ELECTROLYTE, AND MOVING SAID WIRE THROUGH SAID INSULATING LIQUID AND SAID ELECTROLYTE OVER A ROTATABLE METALLIC GUIDE ELEMENT IMMERSED IN SAID INSULATING LIQUID BUT EXTENDING IN ITS ENTIRETY ABOVE THE LEVEL OF SAID ELECTROLYTE AND OVER AN ADDITIONAL GUIDE MEMBER IMMERSED IN SAID ELECTROLYTE SO THAT SUCCESIVE PORTIONS OF SAID WIRE ARE CONTINUOUSLY MOVED THROUGH SAID ELECTROLYTE, AND PASSING CURRENT THROUGH SAID WIRE AND SAID ELECTROLYTE FROM A POSITIVE POLE OF AN ELECTRIC SUPPLY SOURCE CONNECTED TO SAID METALLIC GUIDE ELEMENT FOR ELECTRICALLY REDUCING THE CROSSSECTION OF SAID SUCCESSIVE PORTIONS OF SAID WIRE WHILE IT IS BEING MOVED AND GUIDED OVER SAID METALLIC GUIDE ELEMENT THROUGH SAID ELECTROLYTE.
