Wood firing is a pottery firing technique that involves using wood as the primary source of fuel to achieve high temperatures in a kiln. This process is known for its unique and unpredictable effects on ceramic pieces, resulting in distinctive colors, textures, and glaze patterns. Wood firing is often associated with traditional and artisanal pottery making, as it requires careful attention to the firing process and a deep understanding of how different factors, such as wood type, kiln design, and temperature control, influence the final results.

During a wood firing, pieces of pottery are loaded into the kiln, and wood is burned in a firebox adjacent to, or within the kiln. As the wood burns, it releases heat, flames, and ash. The flames and ash are drawn into the kiln's chamber by the draft created by the kiln's design. The combination of high temperatures, flame, and ash leads to several unique effects on the pottery.

Wood firing is known for its unpredictability. Variations in temperature, flame movement, and wood combustion mean that no two pieces in a wood firing will be exactly the same. This element of surprise adds to the allure of wood-fired ceramics.
