Firing pottery in wood kilns produces fly ash and volatile salts. This complex interaction of ash, salts, minerals in the clay and the flame itself are what give wood fired pieces their unique characteristics. Wood ash might lightly settle on a piece during the firing, or accumulate to the point where the ash drips down the sides of a pot, or the ash might even accumulate around the pot until it is completely submerged. Placement of pieces within the kiln also greatly affects the pottery’s final appearance, pieces closer to the fire may become immersed in embers and ash, while those further from the flame may only be lightly touched by ash effects and salt.
This bowls somewhat misshapen appearance was a natural result of the wood firing process.
