Ash Glaze

Résumé

Ash glaze is a glaze made from the ash of various types of wood or straw. It has been historically important in East Asia, especially Chinese pottery, Korean pottery, and Japanese pottery. Many traditional pottery factories in East Asia still use ash glaze, and it has seen a great revival in studio pottery in the West and East. Through the study, olive ash wood was used and some auxiliary materials were added to obtain wood ash glaze. Wood ash glaze has natural colors that can be improved to a certain extent by adding some oxides. Only this will give color, while the effects of wood ash are controlled primarily by the kiln atmosphere and the firing temperature.
