Understanding Pottery Firing Temperatures
One of the most common questions new potters ask is: What temperature should I fire at? The answer depends on your clay body, the type of firing, and the results you want.
Earthenware (Low Fire): Cone 06 to Cone 2
Temperature range: 1830°F – 2100°F (999°C – 1150°C)
Earthenware is the most forgiving clay for beginners. It fires at low temperatures and produces warm, terracotta-colored results.
- Bisque fire: Cone 06 (1830°F / 999°C)
- Glaze fire: Cone 06 to Cone 04
- Best for: Decorative pieces, planters, tiles
Stoneware (Mid Fire): Cone 4 to Cone 7
Temperature range: 2160°F – 2280°F (1180°C – 1250°C)
Stoneware is the workhorse of functional pottery. Strong, vitrified, food-safe, and durable.
- Bisque fire: Cone 06 (1830°F / 999°C)
- Glaze fire: Cone 5–6 (2160°F – 2230°F)
- Best for: Mugs, bowls, plates, functional ware
Porcelain (High Fire): Cone 8 to Cone 12
Temperature range: 2280°F – 2380°F (1250°C – 1305°C)
Porcelain fires to a white, translucent finish at high temperatures.
- Bisque fire: Cone 06
- Glaze fire: Cone 10 (2345°F / 1285°C)
- Best for: Fine dinnerware, translucent pieces
Tips for Successful Firings
- Always bisque first
- Ramp slowly below 500°F
- Use witness cones
- Keep a firing log — this is why we built The Potters Mud Room.
