Klin effects

Kiln effects (yōhen) is a term that describes a wide variety of spontaneous expressions produced by the interaction of the kiln atmosphere and the surface of the vessel during firing, including oxidation and reduction effects. The cracks, flashing patterns, and natural ash glaze effects on unglazed wares such as Bizen and Shigaraki are famous examples of kiln effects.
