This table is offered as a general guide to proper storage and oven holding temperatures.

• Recondition/rebake procedures for electrode coatings exposed to moisture are included.
• Remove electrodes from containers before placing in ovens.
• Electrode coatings should not be exposed to the rebaking temperatures without first being reconditioned at a lower temperature. Failure to do so may result in breakdown of electrode coatings. After REBAKING, lower the temperature to HOLDING level until reissued.
