Baking: The green electrodes are then baked in a furnace at temperatures of up to 1,200 degree . This process removes the volatile materials and converts the carbon paste into a solid carbon structure.

Re-baking: The electrodes are then re-baked at even higher temperatures, up to 3,000 degree , to improve their strength and durability.
