Why Elements Need Break-In

Fresh elements are springy and must be heated once to oxidize and lock into shape, improving longevity and firing consistency.

Oxidizing New Elements

Fire an empty kiln to mid-range (Cone 04 or higher) to eliminate stretch and create a protective oxide layer.

Thermocouples Work Out of the Box

Unlike elements, thermocouples provide accurate readings from their first heat cycle and do not require a special burn-in firing.

No Burn-In Required

Install the probe, tighten connections, and resume normal firing—no extra steps needed.

Resetting Thermocouple Offsets

Old probes can drift; you may have added a controller offset to compensate. Replace the thermocouple and zero out any added correction (often +18 °F when using ceramic protection tubes). 

Checking Controller Settings

Navigate to the offset menu on Bartlett or comparable controllers and restore the factory value before your first firing with the new probe.

Best Practices for Installing New Thermocouples

• Handle the wire junction gently to prevent damage.
• Keep the sensing tip flush with the kiln’s interior wall.
• Use Type-K or Type-S wire and ceramic protection tubes specified by the manufacturer.

Handling & Placement Tips

Avoid bending the probe sharply; secure leads away from hot element terminals to prevent electrical noise.

By skipping needless burn-in cycles and resetting any offset, you’ll enjoy accurate readings and longer thermocouple life right from the first firing.
