# Running a test fire

*This page is a work in progress.*

After some kiln repairs it may be required to run a test fire. Typically this will happen after a relay or element replacement to ensure the kiln is operating normally.

1. Empty the kiln, if not already done.
2. Place a shelf at each zone with pyrometric cones to record temperature. 
    - Each set of cones should consist of 1 below target temperature, 1 at target, and 1 above target.
    - No other pieces should be fired.
3. Run the kiln's program normally.
4. Record the runtime and cone behaviour.
5. Compare kiln performance against [Expected performance](https://docum.ents.ca/books/pottery/page/expected-performance "Expected performance").
6. Make repairs and [Troubleshoot](https://docum.ents.ca/books/pottery/page/troubleshooting "Troubleshoot") as required.
