How to Use This Calculator

Enter how many firings you do per month on average, counting both bisque and glaze firings.
Select the highest cone you typically fire to: 1 for cone 06, 2 for cone 6, or 3 for cone 10.
Enter how many months it has been since you last replaced the elements.
Enter the total number of firings completed on the current set of elements.
Read the estimated firings remaining and months of life left based on typical element lifespans.
Use the health percentage to decide whether to replace elements proactively before a critical firing.

Firings Per Month: Average number of firings you do per month. Includes both bisque and glaze firings.
Typical Max Cone: Highest cone you typically fire to: 1 = Cone 06 (~200 firings life), 2 = Cone 6 (~125 firings), 3 = Cone 10 (~65 firings).
Element Age: How many months since the elements were last replaced.
Total Firings Done: Total number of firings completed on the current set of elements.
