oxidation firing

Oxidation firing is a process used in ceramic and pottery kilns where oxygen is present during firing. In this environment, the kiln's temperature causes certain materials in the glaze or clay to react with oxygen, resulting in specific color effects, such as bright reds or yellows. This process differs from reduction firing, where oxygen is limited, leading to different colors and finishes. Oxidation firing allows for consistent, predictable colors and is commonly used in functional and decorative ceramics to achieve desired aesthetic qualities.
