1. A method of manufacturing electrodes, the method comprising the steps of:
a) attaching a first electrode to a first reusable header; wherein said reusable header includes a shaped first end;
b) heating the first electrode to a temperature sufficient to melt said first electrode;
c) depositing the molten metal from the first electrode into a crucible;
d) solidifying the molten metal to form a second electrode, where said second electrode has at least a portion molded to be
complementary shaped to the first end of the first reusable header;
e) inverting the second electrode;
f) interlocking the shaped portion of the second electrode with the first end of the first reusable header; and
g) melting the second electrode to form an ingot of increased purity.
