Using zirconium oxide oxygen probes for potters
CarboProbe CP oxygen probe developed for potters, ceramic kilns, industrial furnaces & incinerators
Zirconium oxide oxygen probes are an invaluable tool for potters wishing to control and optimize firing processes in their kilns. These probes enable precise measurement of the oxygen level in the kiln atmosphere, which is essential for controlling the reduction and oxidation (redox) reactions that directly influence the appearance and quality of ceramic parts.
Operating principle
Oxygen probes work like an “electronic nose” for the oven. They use a special material that reacts to heat and measures the amount of oxygen present in the air.
By comparing the kiln interior with an external reference (reference air supplied by a small hand pump), they give a precise indication of the oxygen level. This helps the potter to adjust firing conditions as required.
Description of Econox CarboProbe CP probe

Concrete example of reduction and oxidation
Imagine a potter who wants to create spectacular glaze effects on a series of stoneware vases. He uses a glaze containing iron oxides, which can produce a variety of colors depending on atmospheric conditions.
Oxydation phase:
During the heating process, the potter maintains an oxygen-rich atmosphere. The probe indicates a high oxygen level, and the iron oxides remain in their oxidized state, producing red and brown hues on the glazes.
Reduction phase :
On reaching a high temperature, the potter reduces the air supply and introduces an additional fuel source (e.g. propane or wood) to create an oxygen-poor atmosphere. The probe signals a drastic reduction in oxygen. Under these conditions, iron oxides transform into their reduced states, producing blue, green or black colors.
By precisely controlling these phases with the probe, the potter achieves consistent, breathtaking results, while reducing the risk of defects.
A smart investment for long-term savings
The acquisition of a zirconium oxide oxygen probe represents a strategic investment for potters. Although the initial cost may seem high, the long-term savings are substantial:
- Reduced losses: Fewer defective parts thanks to better control of firing conditions.
- Energy optimization: more efficient use of the furnace, reducing energy costs.
- Improved quality: Consistent, high-quality results increase customer satisfaction and the value of creations.
