Kiln Firing Schedule

Calculate total firing time, peak temperature, and cooling time based on target cone, ramp rate, hold time, and kiln size.

How to Use This Calculator

Select your target firing range: 1 for cone 06 (low-fire), 2 for cone 6 (mid-fire), or 3 for cone 10 (high-fire).
Enter your desired ramp rate in °F/hr — 100–200 F/hr for bisque, 200–300 F/hr for glaze firings.
Enter the hold time at peak temperature in minutes (10–30 min for most firings).
Select kiln size: small, medium, or large — larger kilns heat more slowly and require more time.
Read the total firing time in hours (ramp + hold), the peak temperature in °F, and estimated cooling time.
Add the firing and cooling hours together to plan when to start your firing so you can unload safely.

How the result changes with Ramp Rate

Target Cone: Select firing range: 1 = Cone 06 (1828F, low-fire), 2 = Cone 6 (2232F, mid-fire), 3 = Cone 10 (2345F, high-fire).
Ramp Rate: Temperature increase rate in degrees Fahrenheit per hour. 100-200 is typical for bisque; 200-300 for glaze firings.
Hold Time at Peak: Minutes to hold at peak temperature for heat work. 10-30 min is common for most firings.
Kiln Size: Kiln size: 1 = Small (test/hobby), 2 = Medium (studio), 3 = Large (production). Larger kilns heat more slowly.
